Though I am not done with the Anderson I started, I decided to get the US Bicent. kilt started. I am hoping to pleat to the sett, but I am having some problems.

From the center back stripe to the last pleat after the front apron I have 13 pleats. If I understand correctly, I will need to have 12 more pleats after (towards under apron). Barb's book says the last pleat should mirror the first pleat. However, when I do the 12 additional pleats it doesn't end where it should. If I do 11 it does.

HELP!!!!!!!!!!!
