I have been making these hats for years. Thought that the hat needed company, so I added a matching cowl and fingerless mitts.

The hat used 39g/1.4 oz. of yarn.

The cowl used 35g/1.25 oz. of yarn.

The fingerless mitts used 45g/1.6 oz. of yarn.

The total weight is 119g, which is just over one skein. If you are making only two of the projects, one ball will be plenty!
