my easy to remove design wall
 

I too used flannel over my insulation board.But found that the flannel on the bottom half isn't as "grabby" as the flannel on the top half. I think I am going to redo the board and try it with felt. But I do love it, I had done mine about 6 years ago when I realized how expensive those fancy design boards were, and a sheet of insulation was less than $10. And then there was the $120 for the roll-down like a window shade! No thanks.
I mounted mine on a piece of board and attached hooks to it. Then put anchors in the wall above the closet and hung it there, easy to remove if I need to get in the closet. And simple to remove the anchors when I am ready to sell my house. :o

I have the same design wall, I used flannel.

I made mine the same, with batting, but I don't glue it down. Instead , I just pin it on. Sometimes that piece has just been the right size (and last piece) I had to use. Originally my plan was to mount the 4 boards to the wall, but I soon discovered I like them to be portable.

I have no room, so I use my double bed. Works great for me and it is free. We do need a place to sleep anyway

Thanks for such a great way to make a design wall!

I have one similar to yours that I inherited when someone in my guild enlarged theirs. I would like a larger one but I am out of room. I love it because sometimes when I have larger pieces with lots of seams they don't want to stick like the should and I can just stick pins in it like a bulletin board.
I just took over another bedroom in my house, my DS moved out and bought a house. I was gifted an older model longarm. I plan to put a larger design wall in there someday.

Wowza! This is awsome! I used the insulation panels years ago for blocking knitted sweaters, that stuff has a Lot of uses! LOL

We used the same material, covered in white flannel and mounted on 2 room dividers I got at an estate sale. They can be folded and put away, not like that ever happens. Originally fastened with wood screws. Construction adhesive is the way to go.
