It's finished, at last! I just need to tweak the font colours for the really leafy pages...white is hard to see against a green/brown background.
I am looking at different ways of binding the book once it's printed. I saw a leaflet today which looked and felt good; it was half a strip of A3, folded in the middle and stapled. I am thinking I could easily do that myself, and it'll look okay so long as I print Pipit onto good quality matte bond paper.
