Re: Can't find colored jos, so...........
I have made several sets of weapons. (Much easier than you think). Even a purchased weapon can be colored. I would clear it with alcohol, or mineral spirits - lightly sand it with a fine paper and the stain it. You can use bottled ink mixed with alcohol as a solution and rub it on. My favorites is using ammonia to turn the wood black. However nothing beats beautiful wood grain. Hickory and walnut are great.
I do like you multi-color designs. I have planned to make a kanji stencil and use wax to seal the wood. Then stain the rest, leaving the kanji clear wood grain. I will try it on junk wood first.
