I don't know if this will help you or not, but this pattern is made up of many different hexagons, sewn together. Maybe you could use just the hexagon instructions from this pattern?

see A Gathering of Lace (edited by meg swanson) its a tricky thing to do, they have a pattern for a lace hexagon purse, and lots of notes on how to make a hexagon in knitting (its a Emily Ocker pattern --the same emily ocker of the emily ocker cast on)
