If your not using or sending it to a longarmer & your quilt top is nice & squared, I don't think you need more than an inch or 2 extra for the backing. I pin the sandwich together with saefty pins & then turn over the backing extended edge to the front & pin until I finish machine quilting to the outer edges. This keeps the batting from getting beat up during all the twisting & turning during quilting.

Thanks! (BTW, if someone would adopt me already I coulda saved some folks from reading this, hint hint Lol)
