I really liked my boxwood mitts and had lots of leftover yarn from my 100g ball, so I made a matching hat.

CO 150 sts

Work 12 rows in k1p1 rib
Purl 1 row
Knit in Boxwood pattern from https://www.ravelry.com/patterns/library/boxwood-mitts
When I got to the crown, I worked 6 decreases evenly every 4 rows several times, then every 2 rows several times, then k2tog every pattern repeat every two rows for a while, then more and more decreases intelligently.

This ain’t a pattern so if you do this you can do the crown however you like.
