Just ordered some from fabric.com -- they have some that's $8.40/yd. At 60" that sounds like a good deal. I have a baby quilt I want to use on it and like you have never used it before.
DId you use batting? I'm thinking of not - just the top and the minky backing.
(If you order from fabric.com search for a code - retailmenot has one listed that saves 15%.)
