Layering

I spent a lot of time in Lyon demonstrating how to colour lutradur. For some of the time, I worked small, but this is a section of a larger piece that was added to over two days. I like working with lutradur this way, it can take a surprising number of different layers of colour. Now, though, I have to make some decisions. Do I put this onto something else, or do I use it as it is? Is it strong enough to work on its own, or does it need something else added? Decisions, decisions. Watch this space...
