Finished: "Birds for Gramma" Embroidered Silk Wall Quilt

Birds for Gramma, 14 1/4" x 19 3/4"

In the midst of my Back-to-School Moping, I managed to finish this little wall quilt as a (belated) gift for my Gramma's 91st birthday.  This is the first machine embroidery project I did with the Jumbo Hoop on my Bernina 750 QE machine.  I enlarged and recolored the Anita Goodesign embroidery design (from their Fantasy Birds Collection Special Edition design pack, available here) for a ME Blog Hop back in March, and then I machine quilted the feathers and pebbles a few months later with the BSR foot on my 750 QE as a FMQ challenge exercise in June.  I loved how it turned out, but wasn't sure what to do with it until I was trying to figure out what to send my grandmother for her 91st birthday and my Aunt Debbie suggested "something sentimental."  My gramma was recently moved from her apartment to another care facility where she can get the additional assistance she now requires, but she has a much smaller room and has had to give up a lot of her possessions with this move.  I had Lars and Anders each select one of their best paintings from the art portfolios that came home from school in June to send to Gramma so they could be hung on her walls to decorate and brighten up her new living space.  And I trimmed the edges of this diminutive birdie quilt, added a hanging sleeve, and bound it with a 1/2" finished width red silk dupioni binding to give the effect of a frame.


I really like the dimension and texture I got with this piece, which I quilted very densely around the embroidery design using Hobbs Tuscany Silk batting and YLI #100 silk thread.  The silk base fabric is a lightweight silk shantung drapery remnant from Kravet that came with those gold glitter flecks on it.

I've never put a hanging sleeve on a quilt before and, as with most things I get nervous about and avoid attempting, it turned out not to be a big deal, after all.  I hope Gramma enjoys this.  I'm sure she will love the pictures the boys made!

One more thing: as much as we quilters tend to agonize over and feel guilty about our "works-in-progress" or "unfinished objects," it was really nice to have something almost finished on hand that I could pull out and complete for this gift.  The reason I hadn't finished it in the first place was that I couldn't figure out what I wanted to do with it, but as soon as I knew it was for my Gramma's nursing home wall, I knew exactly what needed to be done.  With that in mind, I may be INTENTIONALLY stockpiling an assortment of UFO projects from now on!

Better Late Than Never: February 2012 FMQ Challenge Completed, Feathers With Diane Gaudynski

Embroidery Disaster Saved by Free-Motion Quilting!
Remember the 2012 Free-Motion Quilting Challenge hosted by SewCalGal?  Each month last year, a different free-motion quilting expert provided an online tutorial with a practice exercise.  We were supposed to complete all twelve by the end of the year, but I didn't even find out about the challenge until June I only managed to complete seven by year's end.  Although I was brand-new to free-motion quilting at the beginning of this challenge, I found that setting aside a couple of hours once a month to practice quilting motifs has made a HUGE difference -- like the difference between drawing with a pen in my hand versus trying to draw with a pen clasped between my toes.  Well, SewCalGal recently announced a "second chance" for those of us who did not meet the goal in 2012, and I now have until October 31st to finish the remaining challenges. 

So, back in April I spent something crazy like 6 hours embroidering this enormous Jacobean bird design, only to have it shrink up and pucker when I attempted to press the finished piece from the back side?  (I have a theory about that, by the way -- I had layered a piece of unwashed muslin beneath the silk shantung prior to embroidering for extra stability, then trimmed away the excess when the embroidery was complete.  I think the muslin backing shrank when I ironed it).  

Ruined Embroidery Project, Ripe for FMQ Practice
I decided to use this ruined embroidery project for FMQ practice, to see whether I could quilt out those ugly puckers and ripples between the embroidered areas.  I spent several hours yesterday and today working on Diane Gaudynski's February 2012 feather tutorial, and I could not be more thrilled with the results.  I have admired Diane's machine quilting, and the machine quilting of her students, for years, and I own both of her wonderful books.  Still, I've not felt up to the challenge of trying to quilt feathers until now.  This is the first time for me just sitting down at the machine and quilting feathers over and over again.  They're far from perfect up close, but much better than I ever thought I would be able to do.  And, thanks to the FMQ challenge, I now know that my quilting skills WILL get better and better, the more I practice.  If I can do this, ANYONE can learn!
 
So yes, I was able to quilt out all of the puckers in this embroidery design, and what's more, I managed to quilt some passable feathers and lumpy-but-acceptable pebble background quilting.  I have long struggled with both of those designs and have been practice-doodling feathers on my iPad for months.  Wahoo!
 
 
Can you believe this is the exact same project as the ugly wrinkled mess in the previous photo?  I almost threw this away!  Now I like it so much that I have to come up with something to do with it.  The finished piece is 16" x 20."  Any ideas?  I suppose I could just square the edges, bind it, and call it a "mini wall quilt." 
 
I'm Quilting Feathers! 
I attempted several different feather styles, but even though the traditional, backtracked feathers are supposed to be the most difficult to quilt, those were the easiest for me -- probably because that's the way I've been doodling them.  However, I was NOT doodling the stem correctly, so all of my stems are a bit wonky.
 
My fabric is a glitter-flecked silk shantung layered with Hobbs Tuscany Silk batting and muslin backing.  I used #100 silk thread in the needle and 60/2 Mettler cotton embroidery thread in the bobbin, with a size 60 Microtex needle, tension reduced to 1.50, and BSR stitch length set to 1.5.
 
It even looks cool from the back, see?

So now that's one more down, and only four more to go.

Pernicious Puckers and Detestable Thread Loopies: Trouble-Shooting in Machine Embroidery

Okay, so remember the Big, Bodacious Birdie that I spent the better part of two days embroidering for the Machine Embroidery Blog Hop a couple of weeks ago?  I promised I would do a follow up about some of my trouble-shooting, and here it is.

I really need to do a huge disclaimer here first to let you all know that I am NOT a very experienced machine embroiderer.  I have embroidered monogrammed gifts here and there, a quilt label or two, and a couple of Bob the Builder designs on tiny little sweatshirts, and I have done some outline quilting with my embroidery module, but that's about it.  Now that I've invested in a new machine with superior embroidery capabilities and a great, big Jumbo Hoop to go with it, I'm determined to do more embroidery than I did in the past, and I'm hell-bent on solving the most irksome problems that have plagued my machine embroidery projects from the very beginning: Pernicious Puckering and DetestableThread Loopies of Doom!

Puckering with Organ Titanium 80/12BP Embroidery Needle
So, for the ME Blog Hop, I tried to follow the Anita Goodesign directions to the letter, but the directions were specifically written for the applique block designs and I was embroidering an individual, NON-applique motif that I had enlarged by about 10-12% in my Bernina embroidery software.  I noticed some puckering around the fill stitching with the very first thread color, but I didn't stop and start over because I honestly didn't know what to change and I had to get the design stitched out and the post written up for my blog hop deadline.  I decided to use this as a learning opportunity, knowing that I could use the finished design for free-motion quilting practice if it turned out really awful and unusable.  So I stitched away...

I take a scientific approach to these kinds of problems.  Step one was the research phase, where I read several books on machine embroidery and compared advice from different authors.  (See my book reviews here).  As soon as I noticed that my birdie design was puckering, I got the books out again and started hunting through them for ideas.  I had learned that puckering is usually a symptom of stretching the fabric when you're hooping it, but that puckering can also be caused by insufficient stabilizing or by using a ball point needle when a sharp needle would have been more appropriate for your fabric.  Since my silk fabric had been interfaced with Pellon Ultra Weft, then spray-basted with 505 to a piece of muslin that was spray-basted to a piece of midweight tearaway embroidery stabilizer, I thought for sure I had the stabilizing part of the equation under control.  With all four layers sandwiched together and then starched, it felt like I was hooping a piece of card stock instead of fabric. 
 
The first color in this design was a dense fill stitch for the top bird, but most of the subsequent colors were satin stitched elements, and lordy, how the Loopies of Doom reared their ugly heads! 
Behold, the Detestable Thread Loopies of Doom!
I knew I could fix these ugly upper thread loops after the design was finished (I'll show you how later in the post), but there were SO many of them and honestly, I knew I must be doing something wrong and I was determined to figure out what it was.  These upper thread loops have plagued my embroidery projects from the very beginning, when I tried just cutting them off (bad idea -- it makes your whole design unravel!).  My preliminary internet research revealed that many people think this problem is just inherent to domestic embroidery machines, or that it's more of a problem with certain machine brands than others. Not so! These upper thread loops, which are most common with satin stitches, indicate that there is an issue with the upper thread misbehaving as your needle passes down into your fabric to form a stitch. Our variables are the needle, the thread, and the fabric.  So I experimented with changing one variable at a time, taking notes about what I had tried and what results I noticed, before changing a different variable.  The first suspect is the needle, so I started changing them out after each color change and taking notes on what I had tried so far and what results I was getting. 
 
H80/12TBP = 80/12 Titanium BALL POINT!
I had started out with one of what I thought was the best embroidery needles in my drawer, an 80/12 Organ Titanium Coated Embroidery Needle.  Titanium coated needles last 5-7x as long as chrome plated needles, so they are worth the higher price point.  But what did this give me?  Thread loopies!  I put in a new needle of the same type, brand and size, in case the first needle had a burr or defect.  Still thread loopies.  That was when I noticed that my package said BALLPOINT embroidery needles.  One of my books had explained that most of the flat shank embroidery needles sold for domestic (non-commercial) embroidery machines had a ballpoint tip, whereas the round shank embroidery needles for commercial machines came in a much greater variety to suit a wider range of fabrics. 

90/14 SHARP Embroidery Needles
Aha!  I dug around in my drawer (it helps to have a stockpile of lots of different needles) and tried a size 90/14 Organ Sharp Embroidery Needle.  Guess what?  Once I had switched from a ballpoint needle to a sharp point needle, I saw no more puckering with this design, even when the second bird stitched out with the same dense fill stitch that caused puckering right out of the gate.  I still was seeing thread loopies, but fewer than before. 

I consulted my book again, the one about embroidering on "difficult materials," and saw that the author recommended using a MICROTEX needle instead of an embroidery needle when embroidering a densely woven silk fabric like mine.  More digging in the needle drawer yielded a pack of 70/10 Schmetz Microtex needles.  DISASTER!  Uber thread loops!  Eek!  The size 70 needle made a hole that was much too small for the 40 weight Isacord embroidery thread to pass through smoothly. 

The Winner!!!
Finally, I put in a larger 90/14 Schmetz Microtex Needle, and my thread loopies were almost completely eliminated.  If you think about it, this makes sense.  Microtex needles are designed with a very slim, acute point, for precise stitching through densely woven microfibre, silk (like my silk shantung!), satins, and artificial leather, and the larger 90/14 size was better suited to my thread.

I said that the 90/14 Microtex needle ALMOST eliminated all of the thread loopies.  I eventually figured out that the remaining loops resulted from the way the slippery embroidery thread was falling off the spool too rapidly, reducing the tension on the upper thread even though it was properly threaded through the tension disks.  I had started out with my embroidery thread on the horizontal spool pin, then tried it on the machine's vertical spool pin (I didn't like how the larger embroidery spool wobbled around there) and finally put it on a free-standing cone thread stand next to my machine to facilitate speedy color changes (this was before I got the adapter to attach my Multiple Spool Holder to my new 750 QE machine).  I was using the thread net thingy with the first couple of colors on the horizontal spool holder to keep the thread from unwinding too fast and getting caught, but I stopped using the net when I went vertical with the thread because it was slowing down my color changes, I was lazy, and didn't believe the thread net was doing anything anyway.  Wrong! 

No Thread Net
See how slack the red embroidery thread is in the photo above, how it drapes between thread guides on its way to the tension disks?  Somewhere I read that these ugly thread loopies can be caused by upper thread tension that is too loose, but I couldn't believe that the default embroidery tension on my fancy-schmancy new machine would need to be adjusted for plain old Isacord thread. 

Thread Net to the Rescue!
Noticing the slack in my embroidery thread as it fed to the machine, I decided to try putting the silly little net thing on the thread (it reminds me of the hair nets worn by lunch ladies in school cafeterias).  Believe it or not, this silly little fishnet stocking thing immediately corrected the upper thread tension, eliminating the remaining thread loops.  Who knew?!

This is how the thread looks at the back of the machine when I have a thread net on the spool:


Thread Delivery is Taut When Using Thread Net on Embroidery Spool
See how nice and taut it is, with no loose slack between the thread guides?  So finally, after 3+ hours of embroidery, testing out four different kinds of needles and several different setups for upper thread delivery, I finally figured out that Microtex 90/14 needle + Thread Net = No Puckering or Thread Loops on Silk Shantung!
 
Here's that finished design again, still in the hoop.  You can see the initial puckering and horizontal wrinkling that I had with the first ballpoint embroidery needle around the body and tail of the top bird.  All of my thread loopies are still in the design at this point as well.
 
Remember that ugly thread loopy photo I showed you at the beginning of this post?  Here it is again:
 
And here is that same portion of the embroidery design, after I pulled the thread loops to the back of the design with a simple sweater pull repair tool that cost less than $2:
Thread Loopies Gone!
 
Essential Embroidery Tools: Hemostat, Curved Scissors, and Snag Repair Tool for Thread Loopies
These are the three most important embroidery tools that did NOT come with your machine.  The curved scissors at the top of this photo is perfect for trimming jump stitches while your design is stitching out.  The snag repair tool at right gets inserted into your completed embroidery design from the right side, right next to a thread loop.  You simply twist the tool slightly as you pull it through the embroidery design, and it catches the thread loop and pulls it to the back side of your work. 
 
So, what's the other tool in that photo, at bottom left?  It's a hemostat.  It looks like a scissor/tweezers but it has serrated edges that tightly grip as little as a single slippery embroidery thread when the handles lock together. 
 
Because I hate to waste bobbin thread, I keep sewing until my bobbin completely runs out, and I end up with 5-7 satin stitches of white bobbin thread on the top of my design that I have to remove before I can back the machine up and continue embroidering my design.  I use my curved scissors to clip through the center of those satin stitches from the right side of my design (without severing the top embroidery thread), still in the hoop, and then I can grab one side of the clipped satin stitches with my hemostat tool and pull them all out with one tug.  Easy-peasy!  Then I just back the machine up those few stitches and continue embroidering the design. 
 
Lest you think that I have finally solved all of the mysteries of machine embroidery, let me show you what happened when I unhooped this design:
 
This excess fabric and puffiness in between embroidered areas is a different kind of puckering from what was happening with the ballpoint needle around the top bird.  I think the slippery silk fabric slipped loose at the edges of my hoop, and I think this because my "embroidering difficult fabrics" book advised wrapping the inner hoop with self-adhesive VetRap to prevent this problem with silks. 
 
Remember how I said that I tried to follow the Anita Goodesign instructions as much as possible, but their directions were for an applique block?  They were having you hoop only your muslin and stabilizer, and then overlay your silk fabrics as applique pieces that would be secured individually as part of the embroidered applique process, so their silk wasn't in the hoop at all.  Although I had four layers sandwiched together for this design, I noticed upon completion that the Pellon Ultra Weft interfacing was pulling away from the silk in places and that the 505 spray had not prevented my silk fabric from separating and moving away from the muslin and tearaway stabilizer that it was hooped with.
 
Since I had spent over four hours stitching out this design, I tried to "fix" this problem by ironing the completed design from the back side, face down over a terry cloth towel, as I have heard many people recommend.  Hmmm...
 
After Ironing!!!  :-(
I am NEVER GOING TO DO THIS, EVER AGAIN!!!!  Surely you heard my lunatic screaming reverberating around the planet?  Apparently, I don't know how to iron, either!  Soon after this picture was taken, my darling husband spilled COFFEE on this design, too.  So this stitch out is destined for free-motion quilting practice after all.  It will be interesting to see whether I can quilt out all that excess waviness in the design with close echoing or pebbling or something, and I can practice other designs around the embroidery.  But I have NOT given up on this.
 
I'm going to try this design again, using the 90/14 Microtex needle, but next time I'm going to:
  • Wrap my inner hoop with self-adhesive bandage tape to better grip the slippery silk
  • Engage my machine's basting function to secure all layers around the hoop's perimeter prior to stitching the design
  • Try a different fusible interfacing for my silk fabric.  I brought home two different options from Sew Much Fun the other day, products specifically designed to support dense embroidery designs on lightweight fabrics without changing the hand of the fabric
I'll let you know how that works out!
 
UPDATED 6/17/2013:  I was able to save this project with free-motion quilting!  You can read about that in this post.
