When you work stripes of colour in the round you will get a 'jog' between the end of one round and the start of the next round. This is because when you knit in the round it is a spiral and the start of round is where you spiral to the next level.
This is a easy way to avoid the jog:
- Knit the first round with your new colour.
- At the start of the next round pick up the stitch from the row below the left needle and place it on the needle tip.
- Knit this lifted stitch with the stitch on the needle.
