Since the Merrill bracers themselves were probably going to be out of most people’s price range, I’ve gone ahead and posted the pattern for free, because I luv u nerds.
Didn’t have time to make proper, printable scans, but it’s laid out on a 1" grid so it should be easy to figure out. The straps are riveted to the back piece and then criss-crossed such that the rivets don’t show, tacked down temporarily with contact cement and then stitched around the edges to keep everything strong & tidy.
I used 4-5 oz veg-tan leather for this, but craft foam would probably make a decent (if more delicate) substitute. The straps for the wrists I riveted on at the A3/B3 holes, and the straps for the forearms are riveted at A9/B9, then both are included in the edge stitching. The length of those straps should be arm/wrist circumference + 4".
That pattern gives you way more length than you need for the palm strap, so figure out how much overlap you want, cut off the excess, and stitch it down.
Uhh, I think that’s everything. More angles of the finished bracers here.
And as always, if you do happen to be rolling in money, Armory Rasa can make them for you. ^_^
