I don't pay much attention to fabric lines, just picking out fabrics I like together. I use mostly older fabric as I have a lot of it but I do pay attention to the quality of fabric. I learned that with one of the first quilts I made. I bought good fabric but could not find a purple I like so went to one of the chain stores and picked up a pretty purple. Well 20 or so years later, the quilt was still pretty and holding up well except for the purple fabric which had faded to almost white and was very thin. So I do pay attention to the fabrics I use whether they be old or new. I have lately found new fabrics in quilt shops that are thin, shrink easily, and ravel like crazy. I seldom buy fabric at the chain stores now as I have found them to be more likely thin and ravel more after washing. sometimes they will feel a bit stiff because of the sizing they have in them.
