Today’s project: install a design wall. Check!
That’s 3.75 sheets of 1″ x 24″ X 96″ rigid foam insulation, screwed to the wall with drywall screws, anchored with large washers. I removed 8 inches from each board to get the right height, which was remarkably easy to do for a quilter. Since each sheet was 24″ wide, my 24″ ruler fit perfectly. I lined the ruler edge up with the factory cut edge (much straighter than a fabric edge!) and used a box cutter like a rotary cutter to score the sheet. A couple of snaps and I had a fairly clean cut.
