Good looking bow!
I'll tell you what I use more than anything to stain, and it's free. Every fall I gather a few 5 gallon buckets of walnuts only half full. I place another bucket inside to kind of seal it all in. after a few weeks, they start to rot and break down and the hulls get really dark and turn into a nasty goop. Use rubber gloves to smear it on and then wipe most of it off. It doesn't soak in like I would like it to, but I think if I added some alcohol it might help it too. the color is great, if you like dark wood, and the little granules in the stuff make almost like a sanding sealer and you can get a real slick smooth finish. after I get it where I want I use either spray lacquer or tru-oil to finish it.
