Robert,
At most local sporting goods stores they sell a matte finish (so no shine)camo tape. It is used for all kinds of things. I use it on my bows. It is a vinyl tape with an adhesive back, but is not REAL sticky so it comes off without leaving any residue. You can get it in several types of camo (I use the one with the light brownish look) to match your terrain.
I think I picked it up for around $5.oo per roll and did 3 or 4 bows with the stuff. It is thick enough to provide some protection against dents and dings as well. I apply it to the back of the bow (surface towards what your shooting at) then trim it flush along the edge of the limbs.
