Some great lace tips - reposting this link Väkerrellen sent me so it's not buried in the comments.
Yes, the Koigu shawl got frogged yet again last night. Seems I can't count, and 5 x 15 is 70, not 75, in Jane-world. Oh well. I made it into the 2nd repeat today and am using lifelines, which should help no end.
AND I can finally see the pattern in this lace, so that's cheered me up no end!
