Lindsay, from Craft Buds, devised a simple, inexpensive and effective board that can be hung (or propped up) wherever you have the room. White cotton batting is attached to inexpensive insulation board from the hardware store to create a nappy surface to affix quilt blocks to.
Quilt blocks adhere to batting better than flannel and are easy to move around as you’re working out the quilt’s design. Plus, the board is lightweight and can easily be temporarily (or permanently) attached to a wall. You can also store it under a bed when not in use.
If you don’t have wall space for an entire board of sheet insulation, Lowes and Home Depot will cut it to the size you want. Affix it to the wall with nails, hangars or even heavy duty Command strips.
