I may be the last person in the entire knitting world to make a calorimetry....but better late than never because I love this thing!! I actually made this one fairly true to the original pattern that is posted on Knitty. As many other knitters have reported it does knit up a bit large, but I put three buttons on mine and I love that its not suctioned to my head. I do have a scaled down version on the needle right now and I will report to you how that one turns out.
As an avid pony tail wearer, I LOVE the concept of a topless hat! I also found some great recycled sweater yarn made by a gal here in Spokane at a great little new store we have called Sun People Dry Goods. The yarn has some colour variations which creates a neat striping effect. Yes, I just used the word neat.
