I just finished all the pieces to a sweater and have started assembling. I basted in a sleeve and found it nearly reaches my fingertips. They are set-in sleeves. How should I correct this? I need to lose about 2 inches. Should I redo the shoulder shaping and adjust the decreases so that I get rid of the 2" there (that is, take the excess from the top)? Or should I unravel the entire cap shaping, take out the 2" from the body of the sleeve (just below the bound off stitches at the armhole), then continue in pattern for armhole/shoulder shaping? It seemed to match up fairly well when I basted it together.
Also, I could use a little advice on which stitch to use for the sleeve seam, and also for joining the sleeve to the sweater. I made this out of a DK bamboo/silk. Also, how much should the seam allowance be?
