Just follow the instructions with the veniard dye, this part is easy enough.
I am assuming that you are getting untanned skins from rabbits and hares, so if you are you will have to treat them and dry them off first.

If assume you can skin them alright, then you would need to nail them to a board, a nail every inch or so, do not stretch the skin too tight though.
Use salt and alum to cure your skin, firstly, coat the skin liberally with salt, then add alum to it. Allow to dry out, then you are in business. Remember a little dye is better than too much, you can always add more, but like me, canny subtract. Do not bother with red, as it looks bad on both rabbit and hare alike.

GO for it, you got to start somewhere, and best wishes,
Sam
