FAST FAST FAST - Complete this hat in about an hour!

My take on the popular Ponytail/Messy Bun Hat - everyone and their sister was asking me to make one, so I did the Julie version, with

1) seamless construction to show your gradient yarn to best effect,

2) a fast and beautifully easy stitch pattern,

3) instructions and measurements to accommodate any yarn weight and any gauge, and

4) with child, teen and adult sizing options.

Please share results and discuss on my Ravelry board and Facebook CAL page, Crochet-A-Long with JulieAnny.
