I am becoming more and more persnickety about quality fabric. I accept an amazing amount of donated fabric from friends and found on our give away table at quilt group meetings. If the fabric is limp, to loosely woven I will pass on it. When I do have the opportunity to shop for my own choices of fabric, I look closely for texture and weave. Texture to me means it feels solid, but not necessarily stiff and the colors are clear across the whole width/length of the fabric. This is particularly true when I purchase wide back fabric.
