Hot Water Bottle Cosy
8mm needles, using scrap yarn
I cast on 32 for the front, and 20 for the back so the side seams are on the back of the bottle for a smoother appearance.
Cabled 4 back every 11 rows.
Picked up 8 stitches on the front and 10 on the back for the collar around the top, knitted in the round.
2x2 rib increasing to 3x2 then 3x3 every other round
The bottom is left open with loops for buttons so the bottle can be removed if needed.
