I guess one thing that's great about doubling your yarn is halving your time!
Canon Baby Soft, held double
Size 10 needles
I have one more ball of this yarn, which is good because I don't really
swatch for hats, and after knitting this hat I feel like I can make a
better fitting one the next time around.
I really like the length of slouch though, in this hat. And you know what's cool?
It's technically reversible ;)
