Simple beanie pattern suitable for beginners.
Sizes XS and S for children, sizes M and L for adults
The pattern requires 3 colors, hence it asks for 3 50g balls. I think you will have some substantial leftovers.

I used under 100 g for each M sized hat, but used different materials - less wool content.
