Feather added to back pleat.

I used Icelandic Bind Off for bottom, love it, and will use it for the sleeves-- but looser on the sleeves. Not as much stretch as I had imagined.

Sleeves picked up and worked as follows:
K 5 rows even
Row 1: K, Increase 3sts evenly around (every 24 sts starting at center top)
Row 2-5: K
Repeat Row 1-5 for 30 rows.
Do one more increase row before starting ribbing.
