First row - you cast on, then you knit or whatever, and then you join. I am all good with that. However, because my yarn is a bit bulky, I have a bit of a jog where the first row meets the cast on row…do you all close that off with the tail? What is the best way to handle it ???
Yes, you fix the gap with your yarn tail when weaving in your ends. If you are doing your hat in stripes, you will end up with a jog in the colours wherever there is a colour change. That is part of the nature of circular knitting.
This should help to avoid that to a certain extent. If you want to find more on it just google “the jogless jog.”
