This was a reply to a question on cold dyes from somebody else. It should be of help to you.

A lot of supermarkets and similar outlets carry it in smaller sizes for dyeing of textiles. Or you can order it on line from lots of places.
There are direct links to this on my site ( from the main dyeing page).

FOLLOW THE INSTRUCTIONS FOR DYEING WOOL for most fly-dressing materials, using hot tap water. The instructions are clear and precise. Some natural materials tend to come out a lighter shade. Use more dye.
If you use cold water as for cotton, silk, etc, the shades may be lighter. As given in the instructions, vinegar works better for many materials.
Run tests before you commit expensive materials! Once you have done it a couple of times, it is quite easy and results are consistent. Don?t buy big pots of dye unless you want to dye a hundred T-shirts!!!
For dyeing a single cape for instance, only a small amount of dye is required. The DRY WEIGHT of the material to be dyed determines how much dye you need. Doesn?t matter if you use a little more and may help to get the right shade. If you use too little, the shade may be too pale. ( Unless you want a pale shade!).
The source I have given here is for America, Google will give you other sources. When you ask for sources for stuff like this, you have to tell me where you are from!

the 5g ( 5ml) packages of dye will dye a great deal of fly-dressing material and cost about $3.00 If you get the introductory kits, you also get salt etc.
This place has it on offer for 99 cents;

Rit and similar dyes are multi-purpose multi-component dyes which will not give good results in cold water, and hot dyeing rabbit and other skins hardens the skins too much, making them unsuitable for purpsoes like zonker strips etc.
I will add some more info on dyeing in another thread.
