I have bought a bolt for backs. I love it. I make lap size quilts also. I chose a neutral swirly pattern, I think it is by Northcott. But then I am mostly a batiks girl. I use extra blocks as a column on the back to make up the width of the quilt. Something else I have enjoyed having is a bolt of fusible web. I purchased that for a necktie quilt and had "tons" left. I am not down to less than a yard and plan to purchase more soon.
