As usual, Sian got right to the heart of my difficulties with this chapter and realised (as I was too close to see) that I was thinking too much and trying to make everything "neat" and "accurate" instead of working intuitively. I had missed the whole point of the chapter, which was achieving exciting and rich texture through cutting and seaming. Once I had "permission" not to be so exact and cerebral, the chapter suddenly became fun - a gift rather than a chore.
I started with my fabric sample and started chopping it some more, not thinking too much but just acting on instinct. I was able to take it quite a few more stages before it refused to feed through the machine any more.
