Hi there. So I'm trying to knit my first pair of socks with a fair isle pattern of three colors, and I don't know to avoid the holes at the join from changing colors. I'm still at top of the sock where the stripe section is and there are 1 or 2 rows of color. Also, the rows aren't even and after researching, I think I know how to "jog" the rows so I don't get the spiral look, but I still don't know how the color change works at the join to avoid holes? Do I let the colors I'm not using hang until I come back around or should they be knitted in? Does the new color tail get knitting in? If so, how do I do using the continental method. Thanks for your help!
