Modified for yarn size and to make smaller for my kiddo.

Casted on (using ribbing cast on) 60 sts with size 10 needles.

8 rows of k1p1 ribbing.

3 total repeats of the 8-round pattern plus another repeat of rounds 1-4 before decreasing.

Had yarn left over, so not quite a full skein needed, but probably could have done a full 4 repeats of the 8-round pattern.
