Couldn’t resist this pattern, it’s so cute. I’m taking into account what other knitters have said about this hat turning out very small, and I’m reconfiguring the pattern. I’m using a total of 8 colours, to use up leftovers. Cast on 124 sts with 2.75 mm needles (with hindsight, 3 mm needles would have given a bit more stretch). 12 rows of corrugated rib. Changed to 3.25 mm needles and increased to 168 sts. Border pattern worked (repeated 8 times). Increased to 189 sts. Body pattern worked (repeated 9 nines). Decreased to 168 sts. Border pattern worked again . Decreased to 147 sts. Top pattern worked (as in original pattern). i-cord loop to finish.
