A few months ago, I posted a Janky dish towel as my first piece, and since then I've gone onto bigger and better things. I'm currently trying to make this baby blanket. One of the instructions says that you are able to change the color every 12 rows, which I plan on doing. My question is, how do I keep the border the same color while the middle part of the blanket is changing in stripes?

I understand how you can carry yarn up for stripes, but what I don't understand is how to carry yarn across. Can you carry yarn across? I'm sure you have to be able to. I'd rather not have to cut and weave constantly, and I only have one skein of the border color. Any advice is appreciated! I can't find anything on YouTube, but I might not be asking the right question. Below is part of the pattern so you can have a better idea of what I'm asking for.

15th Row: K6, **(p4, k4), repeat from * to last 10sts, p4,* k6

16th Row: S1, k5, purl to last 6sts, k6
