Double knit poly wasn't hard to sew on, some had a little more stretch than others, but my gosh, I made lots and lots of clothing from it and stretching never was any problem. I even made a full length robe out of it , black top and patch work skirt. It was cute! Later cut off the skirt and made a play pad for my GS. That stuff washed up great and the colors stayed bright. I also used the poly called Quiana( SP? )It was thin and slippery, but it sure draped pretty in dresses. That I wouldn't use in a quilt!
