R2D2 Where are you?

 This was my first 'free form' crochet project ever.

My son came to me one day and said that he wanted a R2D2 hat.
I had no pattern, but I had seen pictures of other hats online and I thought...How hard could it be?"

Apparently harder than I thought. 
I had to 'rip it out' several times until I got the size right, but once I got the basic size of the crown correct - things went much smoother after that.

This hat is a jumbled mix of DC, HDC and SC, and I messed up the tension a bit in the middle.
I'm not even sure if I could do it again, as I didn't write anything down as I went along.

But my son loves it...so I guess that's all that really matters.
