I used a staple gun. The staples leave a tiny hole and it's very easy to remove the foam board. I have taken mine down twice and recovered it. The staples sink in the foam and don't show.

I covered my boards with white felt and attached them to the wall with L screws. The long side is threaded and screws into the wall. The short holds the board in place. It only takes a few as the boards are very light weight. You can just turn them to the side if you want to take the board down for any reason and it only leaves a few holes to patch if you must remove them later. You can find L screws at any hardware store in different lengths so you will need the thread plus the thickness of your board.

I used clear plastic mirror hangers (clips) because mine is permanent. With a vaulted ceiling I used (2) 4x8's side by side.

I just lean mine against the wall....or actually against my closet doors. There is no empty wall in my small sewing room. :)

I use ordinary picture hooks. I took grosgrain ribbon and loop it thru a D ring and hot glued the ribbon to the back in the shape of an upside down V.

I use the Command Strips with the velcro on them.

My husband attached it with corner round moulding from Lowes.

I used a staple gun with 9/16" staples, it works very well. There are 6 full size sheets on my wall.

I just screwed mine to the wall and then enjoyed designing. There is always something on it and I have inspiration just looking at it.

I have some T-pins that I used to attach my boards to the wall. They leave a small hole if I ever need to take my design wall down.
