Free motion quilting a t-shirt quilt
I've sewn together a t-shirt quilt that is completely knit fabric on the front, except for the border. There is no sashing between the blocks to stabilize them. I used 911FF Pellon fusible interfacing to stabilize the shirts before I had sewn them together and so far the quilt has been working out without too many issues.
We recently purchased a mid-arm quilting machine and I have already finished a few cotton quilts using the free motion style.
However, the quilt blocks have been puckering while I've been quilting them and I can't stretch them out anymore because I want to keep the quilt fairly even. The borders aren't really allowing them to stretch out either. I'm not sure what the issue is or how to remedy it but there are not many articles online and being new to quilting on a frame I've tried everything I can think of.
While I have no experience quilting on a frame, when I read 'puckering' my chief suspect is usually the tension. If you've already worked on some all cotton (woven not knit) quilts and your tension has been fine, it's time to test.
Make up a small sample with some scraps of the interfaced t-shirt material and play with the tension. Yes, I would go as far as to seam it together to replicate your situation as closely as possible. Then play with the tension until your are satisfied with it.
Furthermore, when you return to your actual quilt, I suggest ditch quilting between the blocks. Ditch quilting is not something that most long-armers like to do...I believe that's because they are so much further away from the seam than if you're working at a domestic sewing machine.
If you are not confident in your mid-arm ditch quilting skills right now, then perhaps stitching 1/4" away from all the seam lines—starting at the top border, going all the way to the bottom one crossing the seams. Then left to right from border to border, again crossing seams.
Either option would help contain the 'spread' within each block instead of pushing it across the quilt.
