I found out that there are coloured etching plates so I thought I'd re-print some of my older etchings to see what they looked like. I really like them, I think they make the work look slightly less seriously than the black print. I also used some graph paper for the middle etching which I think worked really well and I'm going to do more experimenting with graph paper although I will have to get a thicker kind as the graph paper I used was very thin. And perhaps do more with the dots....
