A woman at work "hired" me to knit a hat for her friend before winter break. She asked me how much money I wanted and I told her I'd think about it. The hat took me two evenings, and I used yarn that I've had sitting around for years.
When we go back to school on Monday, I'll give her the hat and let her pay me what she thinks it's worth. I'll let you know what she came up with.
(I initially told her $1000, but she didn't believe me!)
If it was for her, I'd give it to her, but she was specific about wanting to pay me, and any money in my pocket will be more than what was there before.
