Experiments with monotype and watercolour

I've been playing with some printing techniques. The fox print was done by cutting stamps and using black oil-based printing ink, then painting watercolour on top (with almost disastrous results for my best watercolour brush - apparently you have to let the ink dry for several days).
Yesterday I tried monoprint techniques. I rolled water-based printing ink onto a mirror, scraped and wiped out a design, and added a couple of bits of string (does that make it a collograph?)
I laid a failed watercolour painting facedown in the ink (I have a big collection of those, I knew they'd come in handy one day!) and pressed the back to transfer the ink.
This is the result. Now I think I'll try some pastel over the top.
