This design could be modified to be a diffuser by using rip-stop white nylon for the fabric, and the frame size could probably be changed to 36x36 without much problem, though I might start to worry about unbalanced weight at that point, and suggest maybe using a T in the middle of one of the runs for the mounting arm rather than putting it on the corner as I've done here.
But anyway, let's get to it!
I apologize in advance, this is not as detailed a how-to as my c-stand tutorial.
Bill of materials:
Hardware/home improvement shopping list
(3) 1/2" Barb Elbow (these came in packs of two. They're brass connectors that would fit inside flexible rubber pipe.)
(1) 3/4" x 1/2" x 1/2" Barb Tee
(1) 1/4" nipple pipe
(1) 3/8" 10' threaded rod
Fabric/Craft Store shopping list
(1) Blackout Cloth, 1 yd @ 54" wide
(1) Black Craft Felt, 2.25 yd @ 72" wide
(1) 1" x 3' self adhesive velcro
(1) Black thread if needed.
Tools Required:
Hack saw or bolt cutter
Hammer
Scissors
Sewing Machine
Ok, this first half is pretty straight forward. First we need to cut the four sides of the frame from the threaded 3/8" rod. We'll be doing a 18" x 36" flag, and the sides need to be cut 2" shorter than the target outer dimensions of the flag. So in this case, two 16" long pieces, and two 34" long pieces.
Now we coax the cut rod pieces into the elbows, it likely will take a hammer and some doing to get them to go in. Remember on the Tee joint it should be threaded rod going in the bottom and side, with the 1/4" nipple pipe should be coming out the top.

Once all the rods are in place it will look like this:
