Yarn: Caron Simply Soft in chocolate (medium brown) for main boobie, about 35 yards; Cascade 220 in 8555 (black) for nipple, about 2.3 yds.
Needle: US size 4 circ
Directions: I cast on 48 stitches in the brown yarn, joined in round. Knit about an inch in k2P2 ribbing. Knit stockinette stitch until hat was 4 inches tall, then started decreases over 8 repeats. When I’d decreased down to 24 stitches, I switched to the black yarn. I added the piercing on the round where I took 16 stitches down to 8 (k2tog all around), then did 2 rows of knitting without decreases. Finally, I did k2tog to reach 4 stitches and knit 2 rounds straight. Then I cut the yarn off and wove it through the 4 open loops and drew the yarn tight. Then I wove it down into the inside of the “nipple” and wove in all the ends. Done!
