I usually order several yards of fabric, and when I'm working with them I fold them S-wise; meaning, I fold it from side to side starting at one end until I get to the other. That way I have a stack I can gradually unfold as I'm cutting, and I don't ever have to worry about over or undercutting my fabric. It's also helpful in cramped quarters like mine, because I can stack them all up on top of each other and just swap out 'bolts'.
