They are a little bit more expensive to buy as fat quarters. But if you want to get a lot of different fabrics that are useable, fat quarters are a way to go.
I rarely buy fat quarters unless they are really inexpensive. I prefer yardage myself. I get a min of 1/2 yard if I don't think I will use it for much else. Mostly I buy a yard, if I really like it and it's a good price I get 3 yards and if it's a really really good price I get more!!!!
