Next I seamed together two 45" widths of white flannel that were 3 yards long. I cut one panel in half verically and sewed the halves on each side of one 45" wide panel. Then I laid a cheap polyester queen size batting on the floor and laid the board on top of the batting. The batting was pulled tight around the board and stapled on the back. I repeated the process using the flannel panels pulling the flannel as tight as possible.
DH then attached 1" X 4" boards to the wall where the board is installed. We then attached Velcro to the boards and the back of the design board. DH was careful to align the Velcro on the wall with the Velcro on the design board. Using Velcro allows me to easily remove and re-cover the board when necessary or take the board down and move it somewhere else. I also use the board for a photo backdrop so the seperation between the board and the wall allows me to change out backdrops easily. Once the board was up he did use a small finishing nail in each corner to help secure it to the boards.

As with any project there is something I would do differenly if I do it again. With this board I would certainly use either clear or white duct tape so it won't show through the cover fabric. The flannel I used was $1.00 a yard sale flannel from JoAnn's and it has a lot of stretch to it. I will likely re-cover the board with felt later.
Here is the finished product and I love it. It is the biggest design wall I have ever large enough lay out a queen size quilt.
