Here, here, here, and here are some pictures of knit hats that Mike wore. You can see that one of them had a little panel with buttons - which would be utterly fantastic. It will need to be long enough, however, to at least cover the tops of my ears (and really, hopefull most of my ears) thus actually staying on my head. Preferred yarn: cotton or cotton blend. Wool makes me itchy. I have no idea if hats are even feasible in cotton. I guess it has to be stretchy somehow?
Let me know if anyone, anyone at all out there thinks this would be a fun project and would accept cash and materials to do it.
 I forgot to mention this sermon I found while seeking hat patterns. I was with him on Matthew 6:19 but after that things get a little uh, vehement for me.
