This is a simple knit beanie that includes instructions on how to Thrum the hat for added warmth.

The hat instructions are provided for S - M - L with the medium being a “regular” size hat (21” to 22” heads).

Gauge is not very critical but if you are a tight knitter go up one size needle so that the hat stays comfortable with the thrumming material added.

The hat takes about 100 yards for the regular size.
