How Much Fabric To Buy??

Sometimes when I am starting a new project, I just don't know "how much fabric to buy?"  I sometimes spend hours doing mock-up and calculations to figure out how much fabric to buy. Well no more.  The other day I ran across these cool cheat sheets at JoAnn's for figuring out how much fabric you need for recovering chairs, love seats, and couches, and making curtains.
