Hi Tradrick, I'm not the most accomplished bowyer, but I have tried making shelfs out of 2 or three layers of thick tooling leather and then carved to shape and glued to the side of the bow. It makes a nice quiet shelf and, if tapered from top to bottom on the outside edge, it can be easily covered with the handle wrap. I actually prefer a floppy shelf made from a piece of suede or buckskin that is simply tied to the bow or tucked into the top of the handle wrap. The "shelf" flops over the top of the knuckle and will keep bow hand placement consistant and protect the knuckle from the arrow. (Probably the same as Ferret's suggestion.) A couple of months ago there was a bow ( named triceratops) posted here with a horn arrow shelf. The horn shelf looked great, but was probably too noisy for hunting. M-P
