Used left over yarn from http://www.ravelry.com/projects/kaazzaa/2-button-front-po...

Casted on 110 stiches on 2 needles
Knitted in rib until a length of 9 inches.
Decreased evenly over next 10 rows until abt 5sts.. Pulling the thread through these last sts and used this to join the seam. The seam was not bulky as the wool is just so soft.
