To complement the requested superhero baby vest. ;D

These are knit with 7 different balls of solid-coloured yarn.
To accommodate repetitions of all seven stripes, I added one more row at the end of the short row section (don’t forget to wrap before turning, or you’ll end up with little holes on either end). No row of holes, no drawstring. The cuff consists of 20 rows of the purple (since the matching vest is mainly purple too). Super proud of the result! :D
