The cosy is knitted in garter stitch throughout. Two colours are knitted on every row, and the pucker is formed by pulling the yarn not in use across the wrong side of the work. At each end the strands of yarn need to be twisted together before turning and knitting the next row. Two pieces are made and sewn together at the sides, leaving gaps for the handle and spout. The pucker at the edge of each piece has an extra stitch to allow them to be seamed more invisibly.

The pattern looks complex, but it isn’t once you get your head around the colour changes!
