Mary Pat and Uta asked for photos of the Origami jacket laid flat - for structural education purposes no doubt, and as soon as I could wrest the jacket from my Mum (she borrowed it almost as soon as I finished it), I took some more photos.
The pattern is very clever. As gwensews points out in the comments (I love comments!) the jacket starts out as a shrug, with the sleeves and back knit in one piece, then the top and bottom pieces are knitted on, each having a different shape as collar or jacket base.
The pattern is from this book, Knit 7 by Jo Sharp. It is readily available at Australian newsagents and knitting shops ($Aus 18.95) and the pattern is also available in a kit, in two colourways, neither of which are the same as mine. If anyone wants the pattern or a kit I would be happy to act as an enabler. Lovely people in the USA have certainly posted me enough hard-to-find patterns and notions.
