2-3 sections of 1" foam house insulation (available at Home Depot or Lowe's)
Neutral Flannel - I ordered 100" wide flannel from eQuilter.com
Batting large enough to cover your sized board.
Hot glue gun
Decide how wide and tall you want your board to be. I needed to shorten mine as it came in 8ft lengths. My board is 72" wide by 77" tall.
Lay your sections face down on the floor and push the tongue and groove sections together. Duct tape the seams to secure them.
Lay your batting and flannel over the section and trim. Batting should be about 2-4" larger and the Flannel 3-5" larger than the board section.
I invested the time in steam pressing the flannel. I used a little "Best Press" light spray starch. It turned out nice and smooth.
Now lay the flannel on the floor, then the batting being careful there are no stray threads or any between them. Smooth everything out nicely.
Carefully center the board on top.
This is my favorite glue gun. It is a cordless heavy duty one. I've had it for years and it comes in handy for all sorts of projects.
Pull the flannel and batting around to the back and glue down. When you've done one side, be sure and pull any slack from the other side before glueing it. Glue the center then the edges on the corners. Don't sweat it too much as you won't see it when installed.
Here is the tricky part. Installing it. We had several false starts as you can see here. At first we tried dry wall anchors. We kept hitting studs and ruining the anchors. We really boogered up the wall and ceiling and didn't we?
Coco is so over this whole thing.
Here is the finished board. If you don't want to install it, you can lean it up against a wall, or slide it behind the door or store under a bed.
Using a stud finder, we nailed mine into studs with 3 inch carpenter nails.
Hooray! Here you can see the side. You can pin your layered pieces into the foam.
I installed mine at the top of the wall because of the outlets. If I need to, I can pin blocks at the bottom.
