I use fabric from quilt shops, thrift stores/yard sales, Walmart, JoAnns and Hobby Lobby as well as buying online.(Actually, I love Hobby Lobby fabric) I buy what I like if the price is right and the quality is good. That being said, one of the very first quilts I ever made(before I knew anything about quality fabrics) was a baby drag around quilt for my niece. I bought most of the fabrics from Walmarts $1.00yd bin and after 9 years you'd think it would be falling apart but no, it still looks good after being washed a bazillion times.
