The pattern comes in 6m to 8 yrs sizes. I made V the small (12m-2yrs) in the fruity cotton fabric I used for her Christmas present with purple insides. The pattern only has three pieces and comes together super quick. the only tricky part is sewing around the small curves. Also, I hate hand sewing so it was a little annoying having to sew the inside hat into the shell hat.
The only alteration I made to the pattern was to sandwich a cord made from the self fabric into the sides of the hat to act as a strap and pop a drawstring closure on there.
It turned out super cute but on the small side. V will need the next size up in no time even though she's only 16 mths. Overall, this is a great free pattern!
