The hat pattern calls for baby weight yarn and US G/5.00mm hook. Perfect for cables if you don’t want your hat to be too bulky.
The hat is worked from top down.
Skill level: intermediate, if you are familiar with cables, you should be good :)
You can decorate your hat with sew on gems or shank buttons, it gives a nice finishing touch and it will make your handmade hat a “high end” look.
