Ah, the joy of playing with yarn. Yarn! I love yarn and I know you do too. I recently free-handed a hat for no other reason than wanting to play with the yarn, a nice hand dyed skein from Huckleberry Knits. Here's my hat. It's a bit peculiar but I like it.
What do you think? I played around with double crochet, bobbles, and half double crochet to make my hat. If you're interested, this one of a kind hat will go up on Etsy sometime today.
