This is a 4-colour stranded hat pattern, knit from the bottom up, in the round. Cast on your sts, follow the chart making increases and decreases as stated. You may add a large pom-pom to the top, once you are finished or leave it as is.

A little note about gauge- Baby Alpaca Aire is, indeed, full of air and can be easily compressed.
If you were to knit with a standard Aran, such Nepal by, Drops, you may get- 20st on 4.5mm needles.
