I'm going to try to make one of these:
http://cottonmonster.com/portfolio/and wear it over my tshirt every day for forever. It was featured in the current issue of Craft Magazine, along with some other amazing stuff such as:
Knit a scarf that looks like crime scene tape
Bake a better loaf of sourdough
Cook OR Print with squid ink
Tin foil art
