Chef Hat - How To

Hello Kitty Chef Hat

I made this Chef hat to match with apron I made for my DD. It's size is adjustable, fitted well with kids heads from small kids to big kids (even me..yes I tried it too.)
I searched through internet for idea and instruction, I  designed to (kind of) follow instruction on SkipToMyLou, it is very clear step by step instructions but I didn't print it out, also made the hat after midnight ( waaay passed my bed-time)  So I missed some steps, like it's neat and finished seam between hat-top and hat band. I learned from my mistake, I'll remember this if I made the hat again.

Here is my (missed steps) version of chef hat
