It is pretty simple. Get your girth belt, buy some rite dye (I use scarlet), boil some water in a large pot (I think I used like 2 gallons of water), add the dye and stir for about an hour. After an hour take the girth belt out and hang it to dry, I have heard of some people nailing them to a board so that they do not shrink, but when I did mine it did not shrink much at all by the hanging method.
