Very easy, didn’t fit any pattern I found on Ravelry so I made my own. Cast on 18 stitches (gauge is not important)
Knit in garter stitch and then switch colors every 4 rows.
After 2 rows of each color, you will be back on the side the other color yarn is on and carry up that strand by twisting it around the other before you start the first stitch of the 3rd row.
This will make the side cleaner looking. Make as long as you like!
