There are quilt fabric "snobs" who only look at labels and quilters who are careful and choose what will be suitable.
Years ago I used to tell my students, look at the museum quilts made by women in covered wagons and trying to set up homes in sod houses. They used what came to hand. We love what they did.
Learning about fabrics is the best way -- and just look at all the different grades of thread we now have. I went to a lecture on thread and was amazed. Think how many times a bit of thread goes thru the eye of your sewing machine needle a litttle at a time. No wonder that some threads shed and fray more than others.
