Another newbie question

I want to change colours at the beginning of the row, but I can’t find anything about it. There’s a video here for changing colours midrow. Is it the same. Do I just loop a slipknot over the needle and go crazy?

Yup, just start knitting with the new color. You can weave in the ends later.

Don’t loop a slip knot over the needle though because that will create another stitch. Just start knitting with the new colour and when the time comes to weave in ends, twist the two colours together once to avoid a hole.

Thank you all for your help. I’ll get going and ignore the fact that the ribbing looks like a fingerless gopher braided it!
