Sewmuchmore, I am not sure if you want a picture of my design wall or ccb2200's, but I took pictures, just in case.
My room is not large, so I had to stand in the hall to get pictures. The first picture has a quilt on it that I am adding borders to. The second is "naked."
The board my husband bought is used for insulation and is a light purple. It cuts easily with a paring knife. I made mine 70 inches tall, as that is what fit best in my space. I said I put flannel on it, but actually it is batting, Warm and White. I bought flannel but decided I didn't want a seam, and my sister had used batting quite successfully on hers.
I hope this is helpful.
