Red Success.

The dyeing instructions and experiment protocol have been successfully tested:

The results? Two beautifully dyed objects, one set of instructions with notes and corrections, and I've already managed to do the fixing-up and the instructions are sent out. 

(The result this time turned out to be a rather orangey colour, by the way. That might be due to the pre-treatment, or a different batch of madder, or the different alum, or the water, or whatever. Madder. Might drive one madder and madder...)

Now it's time for me to wait and see what will happen. I'm already looking forward to getting the first of the samples and be able to compare them to the original reference. And, well, I guess I could also think about when to start my own homework...
