Busbiegaz – Sorry I missed the answer to your post off my last one.
There have been quite a few posts on the forum about dying basics and Midlander has done an excellent introduction to dying SBS which will be linked in lots of threads. Have a search around.
Dyes? You need acid dyes for fur and feathers which basically boils down to 2 easy to obtain manufacturers, Veniards or Jacquards (there are others, Omega in the UK and Dharma Trading in the States etc.). Veniards have the advantage that the colours are orientated towards fly tying (as you would expect) the downside is that they are smaller and more expensive than Jacquard and the tops on the pots are virtually impossible to get off without spilling dye all over

.
There are other ways, food colouring, hair dyes, turmeric and other natural products. For me though the acid dyes are straightforward and give good results.
A ‘recipe’ book would be great though, but too many people have secret shades


All the best - Steve
