The skins are on. What I did was stain the back of the bow with medium brown leather dye. It has a lot of red and yellow tints in it. The stain really showed through the skins and made the almost white skins pretty dark. The tan elmers glue I used dried clear and let the color through.
The skins are short and only go about 2/3 the way up the limb. One litterly fell apart when I put it on the bow. It was just like wet toilet paper, so I pushed the pieces together gently and spliced in some pieces from the slightly longer other skin. There are still some small holes in the damaged skin but the underlying leather dye makes them invisible. After the skins dried on the bow I blended the repairs with more leather dye.
From the ends of the skins to the tip overlays I stained the back of the bow with more leather dye and sanded it back with a scotch bright pad to match the darker pattern of the skins. I was going to wrap the bow at ends of the skins with a copper colored thread but the invisible transition to the dyed limb made this unnecessary. This is coming out much better than I had hoped.
Of course my wife took off with my digital camera so I it may be awhile before I can post pics.
