I experimented on something I'd been wanting to try for a while. I was in the Peace Corps in the Central African Republic years ago. I've been wanting to make a skull cap inspired by the CAR flag (http://www.thelandmarker.com/Flags/Central_African_Republic_Flag.png.
I wanted to use cotton and to do it by stranding with two colors to get the vertical red stripe in. I used size 5 dpns and think I could've probably gone with size 7s or so. Then for the yellow star, I embroidered a little yellow daisy. If I try it again I might just knit stripes with one strand and embroider the red vertical stripe on top.
