Flannel sheet, duct tape. Good husband who helped.

I made a design for my new sewing studio and used Gorilla tape to join the two 4x8 sheets of insulation board. After wrapping it tightly with batting, I used a staple gun and it worked fine. I was going to attach mine to the wall (I even cut out a section to fit around an electrical outlet) but to the advice of Anna Marie Horner...she suggested I not attach it permanently in case I wanted to lay it on the floor for use. (I took one of her classes at a LQS here in Maine.) I read somewhere that you can use command strips on the wall so you can take it up and down... You can see the outlet cutout toward the bottom between sections of the quilt. [ATTACH=CONFIG]603081[/ATTACH]

I used the T-pins that about 2in. long. Wrap the batting around to the edge of the board and insert the pin into the side of the board. I use enough that I don't have to worry about the batting coming down or them being in the way. This way, if you need to take the batting down to clean it, the job will be much easier. I use flannel for my board and I've taken it down a time or two to clean it with no issues.

i wrapped two fannel backed vinyl table cloths around to the back and duck tape mine down. works great.

I've thought of making a design board but ended up just buying the free hanging Fons/Porter design sheet and then hung w/my favorite invention...command strips tight to wall...I refuse to put holes in my new hse walls and hang everything including my quilts w/command strips...This way they are also easy to swtich out when I want a change.
Works great.

The old one I had, I made a super large pillow case out of a flannelette sheet and just slipped the foam board in it, then tilted it up against the wall near my machine. It made it portable and could be hidden when I needed that space.

I used straight pins to secure the batting along the top of the foam.

I made a design board from the insulation too. I used spray glue & duct tape. The duct tape started falling off, so I will be trying the T pins next because I happen to have a lot of them.

The first one I made was smaller, and I put vinyl on the back that the duct tape stuck to really well. This one doesn't have that on the back. Maybe it should...

I made mine so long ago, I actually had to go look at them to see how I did it! lol. I used a glue gun. I just wrapped the flannel to the back and glued one side. Gave it a few minutes to set up and the pulled it taut and glued the other side. Same with the ends. It was easy and fast.

I too don’t want holes in my walls so I use command strips. My design wall (flannel backed table cloth) has been up for a couple of years with them. I now use them to hang my quilts too, works great.
