i was going to go bigger with this but then i stopped and looked at it, and thought 'that's it'. it's turned out around 50 x 50 inches so around 125cm square and that seemed like a good size. the 'wobbliness' of it while liberating to begin with, got unwieldy towards the end, with lots of unpicking and resewing and generally tearing out of hair and much dispair...WHY won't it lay flat??? i've measured a thousand times! but it's all good. i went through a stage of not liking this very much last night, but this morning, i'm back in love. oh yes.
