A 24 x 24 frame, sits on top of the 2" 703 and 3 1/5" Roxul "sandwich
The gussets lay face down on the roxul to stabilize the pile while I wrap and staple the whole thing initially wrt fiber control.
that material is the sheer curtain/scarf material from Mainstays, at Target or Walmart or on Amazon. The red does a pretty good job of reducing the show thru of the 703
The 60" wide scarf , cut into 40" long pieces can do 1 complete wrap of all 6 sides of a 2 x 2 and not be so snug as to distort the unsupported 703 edge "too" much, but it's feeling thing wrt snug enough . . and seems to look ok with the lights out . . .
(Don't we all?)
There will be a final and more "esthetic" also very AT , wrap
the frame is too have something to staple that wrap to . .
I tried tiny binder clips and fabric glue as once these things go up, not too much handling involved but after about 2 hours , no thanks, but the glue is almost dangerous . .
The underlying notion to be to allow as much surface area open
- duh its a cloud . .
So I made 2 of the squares, easy
the logic being to start from a known and then stare at , measure and re-measure it while I shuffle cardboard , plywood shapes etc. around on the frame wrt spacing, coverage and ideas of how to fill things in.
add a few million trips up and down the ladder
the second pic is my first frame that fits rather well wrt centering for the RTF and butts up, in theory, and hopefully as designed, well to the 2 x 2 square.
the trestle and layout of the Tops is left-right symmetrical but the front / rear symmetry is "off" so I'm going to knock out the second frame wrt LTF
IMO a great project if you like puzzles,
