A Study In Koolhaas

these are my third, fourth and fifth koolhaas hat.  i love this hat and it knits up so quickly, making a great holiday present, but i think i am done with this pattern for a little.  finished b's 10 minutes before he had to take h to soccer this morning. which was great since it is freezing here and he had no hats!!!!

i used malabrigo worsted for all of them.  you can get all of the information on ravelry.
