We've all been there before...I sat with Does & darts for days trying to remember my first handpiecing classes doing open-ended seams and turning the piece to fit...and it doesn't always come back alltogether...rip, rip, I forgot to do this or that. Ugh, take the whole thing apart and start again...One thing I have learned and it works for me is to re-press the pieces after handling them too much..H.
