I too have "seen" some fabric snobs that "must" buy $8/$9 a yard fabric to make their quilts. I personally can't afford that, therefore, I lovingly/laughingly call myself a "fabric snob" because I can't justify spending $60/$70/$80 or more on fabric for just one quilt. I would pretty much be limited to probably one quilt a year at those prices.
Use what you like and what you can afford.
