This spring I did the Red Line yarn crawl, and I spent most of my time (fine, all of my time) in the first two stores I went to: Stitch House and Windsor Button.
At Windsor Button there was a yarn tasting. I had brought needles, and I tried many different skeins of yarn in this little column of Rowan-ness. The rep who was running the tasting had a free pattern, a double knit hat pattern using sock yarn. I think it is this hat (ravelry link), but I don't remember the pattern having ribbing, something you don't need to make in a double knit hat, because the stockinette naturally stays flat.
Should I make the Double Layer sock yarn hat, or continue searching for the pattern (I theoretically have it somewhere in the house... heh)? Or maybe just wing it, making my own double knit hat? It's not like I haven't made double knit items before. Most of them have been flat, but that isn't a reason to not do it.
I need to decide soon, because I signed up for the Puck This January 2011 Hat Trick. Three hats isn't impossible to do by any stretch of the imagination, but would be a lot easier if I had three hat patterns and yarns to make what I want (note, this is a yarn to pattern matching exercise, not a claim I don't have yarn with which to knit a hat. I'm not insane and I certainly have yarn).
So, suggestions for hat patterns? I tend to wear beanies even if they make my hair look ridiculous when I get to work.
