the product is available to buy. It’s a good product for specific uses. Above is some info on specific products available to buy. They each have strengths and limitations.
we constructed several about 4’x6’. It was 2 rectangles one atop the other. It needed cross braising for stability. It leaned against a wall. It could be dismantled.
For 6’ square, I’d recommend a large window frame (of PVC) of 4 sections. We used 3” PVC for outside frame. It’s not heavy.. easily moved by hand. Just awkward.
The cover was felt that had sewn tubes on the edges. We put the PVC into the tubes, then assembled the corners.
It’s been awhile. Since I only used it rarely, my memory is sketchy. The best use was 3-5 day retreats with very little wall space to tack up a design wall. They’re very unstable. Definitely can’t lean against when placing pieces. Very difficult to use pins.
