I went to see the Harry Clarke exhibition in the National Gallery on Thursday and while I was waiting to meet my Mum and brother I bought a rainbow pencil in the gift shop. I used to hate rainbow pencils when I was a kid, but I was looking to try them again recently. There were several different colour variations and this was the last one with the CMY primary colours. It's a lot of fun to sketch with, I don't know if I'd use it for a finished picture, but I am thinking about it.
The Harry Clarke illustrations are amazing and so detailed. The lines are so skinny, I've inked lines ten times the size of his and been worried about them dropping out in print. He took seven days to complete one piece, I have to say I wish I had a deadline that would allow me to put that much into an illustration.
