I picked up a skein of Miss Babs' Kunlun yarn at Rhinebeck two years ago and finally got around to using it a few months ago. I did a pretty simple little hat, but this was the first time I tried a waste-yarn cast-on and tubular bottom hem. I really like the stretchyness and the softness of the bottom edge but I'm not sure I love the look of the rolled bottom edge. It loses the clean smooth finish, but I'll definitely do it again when called for.
And, here I am in my first knit hat with my boy in the first hat I knit for him.
