I have a skin which is ready to tan, I've looked the k tan instructions up online and have followed the process, my problem lies with identifying the bags provided as the instructions list them as a b c and the bags themselves are colour coded. There are 3 bags- one is a big bag with the most substance in and is like green flour- one is like course sea salt the rocks being light blue, light yellow and white- and the last is pure white powder and is a much smaller amount. I need to pickle the skin before tanning, so any help would be much appreciated on deciding which bag to use. Thanks
