Hi, I think your doing a wonderful job..[Your dress last week..was just wonderful..]. and the fact that you did all that work ,trying to salvage your too big garment.. Oh..thats fulfilling the challenge !!! to me...the redoing a fitting problem..is the WORSE job in sewing..
Don't worry about the unfinished UFO...Just move on to the next one..its coming soon.. We will be happy to see the next one..
I give you an A ....on the challenge..
