To make this cup cosy you work in multiples of 11 +1.
I used 4.5mm needles and Abbey Road Sunshine Cotton 100g, Yarn Candy.
Pattern
Row 1 and all wrong side rows: P1, (K2, P6, K2, P1) across
Row 2: (right side): K1, P2, K6, P2, K1) across
Row 4: K1, (P2, K6, P2, K1) across
Row 6: K1 *P2 slip next 3 Sts onto cable needle and hold in back of work. K3 from left needle, K3 from cable needle. P2, K1, repeat from * across.
Row 8: K1, (P2, K6, P2, K1) cross.
Repeat rows 1-8 for pattern. I repeated the pattern 4 times to get my desired length. Then I casted off following the Row 1 pattern.
