Changing yarn colors inline is my jam. I do tapestry crochet.

It’s a little different doing it in the round than in the square. I’m more familiar with in the square and can describe it if you like; I got really good at in the round but it was for a single project I completed over a year ago and I forgot everything about my technique except it was radically different 😅

YouTube tapestry crochet in the round will probably help a lot.
