I used two 4 x 8' insulation board from Home Depot that is 1.5" thick. I used Warm and Natural batting and 505 spray adhesive to attach the front of the batting over the board. I wrapped the edge and brought some batting back to the back and used the old fashioned straight pins that don't have much of a head to fasten the batting to the back. I attach both boards to my wall butting them up to each other and hung them with 3M Command strips that have velcro on them. The boards don't weight that much but I think I used the large size of Command strips. I don't remember how many I put on each board, but by using them I could take the boards down from the wall and make them portable, plus put no holes in my walls for screws, etc. I love them, probably the best part of my sewing room!
