I received a custom order this week for a green and purple striped hat. While I was knitting it, I decided this might be a great time to show other knitters how to knit stripes with NO jog at the beginning of the round. The little blue and purple sample on the left was knit normally and the green and purple hat on the right, was knit with this trick! The one on the right has a much smoother transition at the beginning of the stripes.
Image #1: Begin by starting your new color row and knitting it until the end. (Stripes must be at least 2 rounds in size for this to work. If they are single round stripes, helix knitting is a better option to create smooth stripes, but that is a topic for another day haha)
Image #2: Remove the stitch marker and slip the next stitch PURL wise.
Image #3: Place the stitch marker back. This is the new beginning of the round.
Image#4: Continue knitting until its time to switch colors again!
This trick works because while knitting, the fabric is built up in a spiral fashion. Stripes show this off because each color is built up a little higher than the last. This trick smooths that out so it is not as noticeable.
