When I first started quilting I'd buy 1 yard, then went to 2, now at 3. An experienced quilter once told me to always buy at least 3 yards if I liked it but didn't know what I'd make with it. She said 3 yards was always enough...wouldn't you know it, just recently was looking at a pattern I wanted to make and needed 4 yards. So I'll be getting at least 4 from now on.
