Yesterday we bought some insulation board and I covered it with flannel. Jack put them up beside and below my 4 x 4 feet "wall" and my design wall grew to 75 inches by 62 inches. Well, almost....... I still have one section that will go below the new part on the right.
I was able to put all my DNP blocks up on the wall (there are 4 blocks on the bottom right that are pinned to the ones above). This is probably as large a wall that I will ever need when I get the other board covered and up on the wall.
I think my space has evolved to where it will function well. I have everything I need in places that are easy for me to work in. I like it!
