How to make a Quilt Design Wall

So you've cut out your fabric in various shapes and sizes. You've got a vision, but now what? It's time to design the quilt layout. Often times, we take over the dining room table or a large chunk of empty floor to get a preview of how the colors & patterns will look together. But if you've got an empty wall to use, why not set up a quilt design wall?
Supplies needed:

1 sheet foam insulation (4x8 feet, sold at home improvement stores)
neutral-color flannel fabric (white, cream, or gray works best - amount depends on wall size)
ruler & pen
utility knife
packing tape
scissors
stapler
hammer & nails

Step 1: Measure & mark desired wall size, and use utility knife to cut foam insulation to correct size. (My finished wall was 5x5 feet, so I cut several pieces to tape together).

Step 2: Peel protective plastic off foam pieces.

Step 3: Use packing tape to attach foam pieces together (if necessary).

Step 4: Lay foam board on top of flannel fabric, and cut fabric about 3" larger than board on all sides.

Step 5: Fold flannel to back of board and staple down. (The flannel I used was not wide enough to cover the entire 5x5 board; therefore, I repeated steps 4 & 5 with a second piece of flannel. You could also sew the 2 flannel pieces together).
