Thanks for all your answers, PineyRiverQuilter--your personal fabric store is fabulous! This is how I want to arrange my fabric.
I did go to the Dollar Store and picked up kitchen cutting mats, two for a dollar, and because they were 11' x 15", I cut them in thirds, rounded the corners, so they're 5" x 11" now. Six pieces for a dollar! That's a bargain! They're probably not as rigid as the plastic needlepoint canvas, but I was able to fold a two yard plus piece of fabric on it easily. Thanks for that heads up tip. I even bought an extra set of mats to use for chopping in the kitchen!!
