Having made *hundreds* of these tunics, please allow me to offer a caveat.The pattern makes a full length gown, so the gores are going to be WAY too wide if you shorten it to a tunic.
Also, if you use the shoulder to shoulder measurement to cut the front/back panels, there is an 80% chance that the chest will be too tight.
If you look at Marc Carlson's site, you can see that the Bocksten tunic tapers down at the wrist. The underarm gussets are the pieces which have been cut off the wrist area.
If you send me your address, I'll be happy to send you a cutting schematic that takes 2 1/8 yards of 60" wide fabric to make a Bocksten tunic.
