Don't let your hot water bottle be naked!
Let's face it, hot water bottles are ugly. :P But they shouldn't be! Don't let your hot water bottle be naked! Knit it a sweater! Added matching buttons are not only a super cute addition, but make it easy for removal and washing!
Ok! Let's get started! :D
Using the long-tail cast on, start with 36 sts.
Row 1-5: Work in k2p2 rib.
Row 6-10: Knit 4 rows in stst (ending on a WS/purl).
Row 11: Knit 6 sts, bind off 3, knit 7, bind off 3, knit 7, bind off 3, knit 7.
Row 12: Purl 7, cast on 3 sts, purl 7, cast on 3 sts, purl 7, cast on 3 sts, purl 6.
Row 13-22: Work in stst for another 10 rows ending on a WS/purl row.
Row 23 (RS): Knit across row to end, then cast on 40 sts and join in a round (76). Be careful not to twist stitches.
Using the magic loop method, separate your stitches into two halves (38 and 38), being sure that the rows you did for the bottom flap are centered. (1, 36, 1) This will be helpful when shaping the "neck."
Knit around for the length of your hot water bottle, stopping when you are just below the "shoulders."
