More Laser-Cutting

I'm getting the hang of the laser-cutter now and had my first session using it on my own. As well as the Hebden Bridge fold-up townscape, I'm trying something more intricate - its a concertina format book called Tree House.  Its taking me quite some time to draw up the cutting template in Illustrator so I've only tested the first 4 pages.  It looks like this:

I like the idea of it being a kind of skeleton book structure and the resulting shadow casting. This book is a development from the paper-cut carrier bag I was working on a while ago.  I'm still using the 300 gsm Manila cover paper I got from John Purcell Paper ages ago, with its lovely colour and smooth surface.
