This is a tiny bee keychain, which is really quick and easy to work up. You could probably make it into a no-sew pattern, I'm just lazy and sewed the wings onto the bee. It only took me like 30 minutes, and I'm a slow crocheter, so they're really good for if you're going to be in a craft fair.
I used bernat baby blanket for the yellow(I think it may just be regular bernat blanket), bernat blanket for the black, and bernat blanket for the white. I used a 6mm crochet hook. It's about 2 inches long and 1 inch wide.
I recommend using a invisible decrease, but use whatever you feel comfortable with.
