When I first started making bows, they all got a leather or suede wrapped grip, laced-up on the back. Then I switched over to wrapping the handle with thin leather lace, or suede lace and I love it. It is decidedly more work, but it feels so good in the hand and looks cool, too. I suppose one could just dry-wrap the lace around the grip, but I paint on TB-III as I go along, so it's all permanently bonded on and can't come loose. The material I like to use is either 1/8" wide or 3/32" wide, and about 1/16" thick (flat) suede lace. It comes in every color (I'm partial to the chocolate & dark brown shades) and can be found at the craft/hobby stores.
I also like to reduce the handle thickness down a little extra–keeping it flat on the belly side–then glue a layer of cork to the back & belly sides of the handle and use coarse sandpaper to sculpt it round. Once done, I paint a sizing coat of TB-III over the corked area to seal and strengthen it, before wrapping it with the suede lace. This process makes such a comfy grip and likely also reduces shock in the hand.
My other choice of wraps is #10 or #20 twisted hemp cord (thread), glued down in the same fashion as above, but I also paint it down with a finish coat of TB-III. I like this option for the really primitive-looking character bows, where a fancy grip doesn't look the part.
