Well I don't know when my fingers are gonna be fit enough to build this, but I have downloaded it and shrunk it to fit 4 pages on an A4 card. It still looks quite buildable in this 1/4 size and probably could be shrunk even further. perhaps one day I'll try it.
However ... are you sure you have put up the complete model here? I have 8 sheets, including the Cover Picture, but on first perusal the left hand side of the main structure is missing. Which makes me think there must be another page, which may also have other essential small parts that don't leap to mind.
Yep! A quick search of Patricia's flickr pages gave me the extra page. Page 3 & 4 are very similar. Easy mistake to make.

It's been a while since I strolled through this Flickr site. Guess where I'm going now?
