Read on a few posts on these forums that jelly rolls can stretch when sewing (know I have had some of my own 2 1/2 cut stops start raveling a lot eve n if I set them aside someplace where I want them to not gt touched a lot--and I use quality quilting fabric from quilt stores). Want to find that post to ask if she starches purchased jelly roll strips before sewing. Do know I need to see strips in opposite directions when sewing complete strips full length. Anyone here starch purchased jelly roll strips?
