Scribblebook Wednesday #2 - Pi!

P1010779 Another Wednesday, another wanton baring of my messy, messy notebooks... In this particular installment, I am dredging up some equations involving Pi from the murky depths of memory, in order to calculate measurements for a circular shawl knitted from the outside in. Also, some Celtic knotwork doodles (showing a little of the underlying grids used in construction) and some completely unrelated writing in Greek (I'm trying to learn Greek at the moment... as much as I try to keep my notebooks solely design-focused, sometimes other bits and pieces creep in inevitably!)
