Okay, I've finished my quilt top. It is about 52" square. I have fabric for the backing, if I remember right I bought 4 1/2 yrds. I'm figuring I want 56" square but how do I figure where to cut my fabric? I planned on doing one seam in the backing. If I cut it in half, it would only be in the neighborhood of 52" long after squaring it. Okay, that's another question...how do I square up that much fabric? My living room is small and it is carpeted. It is the biggest room in the house. Help!! I don't know what to do next!!!

Love to all,
