I have what I thought was a great book to show me various quilts that could be made with Jelly Rolls. Well, not so much as there aren't any fabric amounts for the backing of the quilts. Why would they do that? IMO it would take just adding 1 more line of text.
I would like to make one of the quilts and the top measures 58 x 76". How much fabric do I need for the back? I've figured 3 1/2 yards. Please let me know if I'll be ok with that much fabric or do I need more?
