My tea cosies require knitting in the round AND knitting back and forth.
Forget DPNs forever. This is the ONLY way to knit tea cosies - with TWO circular needles. I know. I know. WTC says DPNs. But I learnt something new since then. Something grand.
Always knit the left stitches with the left circular needles and always knit the right stitches with the right circular needles.
It is only the yarn that goes ROUND and ROUND.
And then BACK and FORTH for the sides.
When changing needles, make the first stitch and then pull the yarn firmly downwards to tighten the join between the two needles.
This simple action will eliminate ridges at the needle change over point.
There are two very good reasons for trying out this method. There are only two joins instead of four as with double pointed needles, and the join is seamless, without the laddered stocking ridge that occurs at the point of needle change as with double pointed needles.
There are some really great instructions HERE
I use this method on everything knit in the round, sweaters, socks and the inimitable tea cosy.
NOTE: The photo is a base which turns back on itself to give extra warmth and structure as in the pattern for Rosie Posy and Carmen Miranda and Sandwich Anyone.
