I buy fabric I like where I find it. You will find bad and good fabrics no matter where you shop. I have bought lovely, good fabrics at Walmart and they have some that is very poor. I shop a lot at Hobby Lobby and have never bought any from them I didn't like. I buy a lot from quilt shops and online. You just have to learn good fabric from bad and make up your own mind when you see something you want to buy. Some of the worst I have bought came from a quilt shop and is still in my stash that I will never use except for practice blocks. I have been sewing and quilting for many years and I have favorite's like Tonga, Hoffman, Timeless Treasure, Kona, Moda and Robert Kaufman. I buy what I like and don't care what others say or think about it. I have never made a quilt that I didn't like and wasn't loved by the ones I gifted it.
