Anyone know of an guide to dye tracing? Preferably online.
I'm looking for some information that can be used on an expedition with limited access to resources such as power which seems to rule out brightners.
What are the options? Green stuff or spors or?
Apart from the dye getting through what does the length of time mean? Are there any guidelines?
Thanks
