@basketba11 [I know this comment is a couple years old but I’ll answer it anyway for anyone who wants to try this on a smaller scale.]
This is a standard plaid pattern — all forward knots on the first row, all backward knots on the second row, rinse and repeat. You can use as many (or few) strings/colors as you want!! This pattern looks dramatically different depending on what colors you use and in what order, it’s really easy and fun to experiment with. An example of a smaller basic plaid pattern is #1421 — you can see some possible variations and then try some of your own.
