Here´s how I made the puff sleeves for the Little Lace Vest:
Pick up 33 st on both sides of the armhole and 1 right on top of the shoulder = 67 st
Knit 6 st, pm, knit 16 st, pm, knit 9, kfbfb in the next 5 st, knit 9, pm, wrap and turn.
Knit short rows until 9 st remain to first marker = 51 + 44 st remains
From the front k 12, (k2tog, k4) 4 times, k2tog, k 13, turn
On the following RS rows knit 2tog with one less st between, until you have made k2tog x 5. 57 st remains.
Continue to knit in the round all the way to beginning of row.
Knit three rows k1p1, bind off tightly.
st = stitches
pm = place marker
kfbfb = knit in the front, in the back, in the front and in the back of the stitch (increased 3 stitches)

When working on the vest, decrease less stitches for the armhole to make the shoulder part wider.
