I just used the Crayola paints I had. If you have tubes of watercolors it would be easier. I used brown, black, a bit of red and just mixed them up in some vinegar.
I tried my mixture on several different kinds of wood to see how it would look.
Then I dry brushed some black paint over the first coat of stain. The piece on the left below is closest to the color I want. It's still a little light but I'm thinking one more coat and it will be perfect?
I found that a sponge brush works best for applying the stain. I'm hoping that the wood won't warp. I'll let you know how it goes.
It's kind of like dyeing Easter eggs! :D
