I used DK yarn doubled up, but chunky weight is the perfect weight. And i used 5.5mm needles (and remembered how much I like bamboo needles). My tension measured 12.5 stitches x 26 rows in this stitch (I know this sound like an impossible equation, but each alternate row is worked doubling your stitches, before coming back to the original number, so that 12.5 is the un-doubled number – I hope this will make sense when you read on…) The pot I made this for is a little two cup pot which measures about 33cm circumference. My finished cosy us about 18cm across when layed down flat.
