Welcome Victorious & Ermaadkins!
Victorious, those are all great suggestions. I'll definitely do the slipped edge technique; I'll include it in the demo of how to knit a few rows on straight needles that I'll be doing. I'll probably do the video on joining colors that way too.
I do have a video on using circular needles. There's a few videos on knitting in the round. Hopefully they will address your questions.
Ermaadkins & Earthling, check out the videos on two-color knitting: fair isle and intarsia.
