I've wanted to try a wrist rest and ordered a Grifiti Fat Wrist Rest Smooth Skin, I gather it's the company's latest iteration of it's well-known rest. I originally wanted a wooden rest, but at $50 for a Filco, or $80 for Bird Electronics' rest, I think they are overpriced. So, I made this one out of a better quality piece of pine I had leftover from some project I had done. The rest was cut from a 1" (measures 3/4") by 4" (measures 3.5") piece of lumber. I cut the wood, sanded it, and here it is. If I had bought the wood, the simple rest would have cost about $3. The, dare I call it, project took about 25 total from setup, cutting, sanding, and cleaning a bit of sawdust off the floor. I'm sure many others on GH have made their own wrist-rests.
The wooden rest feels really nice; and I'm not sure the Filco or Bird rest would have an improved feel compared with my $3 rest. So... here are a couple photos of the finished product, GH.
Note: the 17" wooden rest, below, fits my wrists far better than the 14", exact-fit rest, the left edge of the 14" was under the outside of my left wrist.
