I enclosed a pdf with a suggested method of building the frame |
This frame would make for minimal masking of absorbent - if you get a nice fabric and your upholstery chops are up to the task I bet they come out looking sweet... down right furniture grade if you sewed the corner seams [like a slip cover]. It also would be light weight compared to some of the other designs above [they look nice put I'd hate to have to carry em up a ladder].
If you don't mind a less sharp edged panel a simple rectangular frame [like the lower section of the design above but dimensioned so its outside edges matched the size of your mineral fiber panels] will have even less masking [not that I really fear it would matter a great deal] - just stack 4" or more of mineral fiber on the fabric, cover the MF with the wood frame, and wrap the fabric around to the backside and staple.
