4 boards, 1 x 4 inches, or whatever you have
4 c. clamps - the kind you find at hardware store
Long strips of sturdy cloth - old sheets or jeans

The four boards form a rectangle shape somewhat bigger than your quilt. Fasten them together at corners with clamps. Double over long strips of cloth and staple these to your boards the whole length so you have something to pin your quilt to.

Place the frame on chair backs or boxes or whatever is handy to get it up to the right height. You begin quilting on one side and roll the finished quilt under as you go until you can easily reach to center.
