Do It Yourself Stains
There are a lot of recipes on staining wood and some of the ingredients include:
Black Raspberries

Food Coloring
Green Tea
Hot Chocolate
Hydrogen Peroxide
Nails
Onion Skins
Pennies
Powdered Indigo
Red Wine

It is also a good idea after the stain dries to seal the wood with a natural oil such as linseed oil (made from flax seeds) NOT boiled linseed oil or olive oil.
