I was able to purchase very small bottles of Procien Dye at the local art store. I had to readjust the amounts to mix with water, etc. If you live in a large area that has art stores, they will probably carry those dyes. Also I bought the dust mask at the art store, but will probably go to the respirator next time, just for safety.
There is a great tutorial with video by Theresa last summer on dying under the category "where to begin". Also don't forget to make a dust box, there is also a tutorial on that. She does a good job with instructions, then I had the courage to try it.
