I released the new version of the original pattern. It is simplified, but a little bit tighter than the sample one was. The first sample of this hat was made with 3.5 mm hook and DK weight yarn, the number of stitches were divisible by 16. This version is simplier. I used 4.00 mm (G hook) and worsted weight yarn for a fitted looking, the number of stitches is divisible by 12.

Gauge: Crochet Rounds 1-2 and measure the diameter of your circle: it must be around 2.5”/6.5cm
