The basic materials are:
- clothing rack on wheels
- Two 4' x 6' 1-inch thick insulation board
- duct tape
- a white sheet
The two insulation boards are put on either side of the rack and then duct taped together. Then I pinned the twin size flat sheet on one side using regular straight pins. If I find that the pins are not holding when I start loading up the design wall with designs, I'll substitute the straight pins with upholstery pins (pins with a curly-cue at the end).
Nothing fancy, but it does the job and now I can easily move it to get at the contents of the shelving unit that is behind it.
This is the back/other side that I haven't covered yet. I'm going to cover it with black fabric. This way I'll have either a white background or a black background upon which to photograph finished art quilts.
The one thing I may change later is to use a heavier white fabric, maybe flannel, because the sheet is a little thin and you can see the shadow of the duct tape behind it.
