I made some changes to the pattern.
On the hat:
-- Made the I-cord at the top of the hat longer.
-- Worked random purl stitches to give the hat texture.
-- Did 2 more rows of ribbing than stated in the pattern.

Hat: Lolodidit Bumble (yellow)
Body: Black mini from stash
Beard: Rowan Angora Haze (white)
Nose & Hands: Undyed yarn from stash

Bee Buttons: From Textile Garden in the U.K. (my favorite source for buttons). LINK Bumble even has a bee under his beard!
