Make three different sized beanies from only one skein of yarn.

I’m sure there are different ways of doing so, but this is my trusted and true way, and in some cases I even have a bit left over.

Increase deviations from the pattern such as 1dc in first st, then 2dc in the next, and so on, are perfectly acceptable and will not mess up the pattern. Doing less or more rows than suggested will mess up the pattern.
