Started with single stitch and did kfb repeatedly, working as if to make an icord. Once I got to 8 stitches, I arranged to knit in the round with magic loop. Did kfb in each stitch one more time to get 16 total (8 on each needle) and worked up in stockinette until it got to the right height. Added purple in for the cap doing a row of Knit to join, then 2 rows of garter (slipped the first stitch of purple from row 1 to prevent the color jump). Did 1x1 rib for the cap, then did 2 rows of garter before decreasing (unevenly). K1, K2tog around a few rows before threading through and pulling tight.
