Wrist rest for pawhammer

Given my experience with Gold Tone's "dojo" (dobro + banjo), where the strings are quite close to the top of the instrument at the bridge (which I'm quite keen on)--not the case with banjo--I wanted to somehow make an elevated playing surface on which the wrist could rest, thus making for less tendency for the hand to "bounce around". Voila, I found that there are these little pillows one can wear around the wrist. These are designed for computer mouse use (anti-carpal tunnel)...and they seem perfect for what I was after. (You can find them at Amazon.)
