I have been commissioned. My five year old brother has asked me to make him a hat. He saw me working on some secret Christmas knitting today, and decided he needed socks with construction trucks knitted into them. After I told him that that was probably too hard, he settled on a hat. With a gigantic mass excavator on the front.
I'm thinking graphs, I'm thinking multiple colors, I'm thinking DIY pattern, I'm thinking billions of ends to weave into my little boy's hat. I'm thinking bedtime.
