This pair of pages are really a bit of a cheat. The top is the reverse of one of the painted pages which inadvertently got blots of paint on it – now there's a surprise. I added a wash of Koh-i-Noor to blend it all together.
The bottom is a left over from this which I made in August – clearly I had graffiti on my mind even back then. It is plastic bags, ironed to laminate them together and then machined. The left-over bit was just the right size for the page so obviously it had to go in. You see why I call it an unsketch book.
