The embroidery thing is cracking me up. I sew, knit, and make beaded jewellery. In fact, I make the vast majority of my clothes. Every time I put a picture up of something I've made, some well-meaning person will say, "Ooh lovely, will you make me one?" or something similar.
Normally I say "haha no, but here's a link to the pattern!" If they persist, I point out how ridiculously expensive my services would be. Occasionally I rant in private to a friend about how so many people think I should monetise my leisure time.
The other thing is...I'm pretty good, but I'm not a professional. I mean, I'm better at sewing than Jack is at embroidery! When I sew, I can fit my own body well, but I've never had to learn to adjust for someone who's tall or long-waisted or broad-shouldered etc. I'm also lazy at times, and I won't redo something that's a bit crooked or whatever because I'm the one who'll be wearing it. So I can't make things to a professional standard, but if I did lose my mind and decide to take commissions, I would nevertheless have to charge a very high amount due to the cost of raw materials and my time.
Every other crafter I know gets SO pissed off at being offered commissions, told to go pro, etc etc. It's one of the most common annoyances that we talk about - in fact, I was literally discussing this yesterday with a friend who does pottery as a hobby. It's something we all hate.
...so OF COURSE the one person who goes "yes my work is great and I should monetise it" is Jack fucking Monroe. Of course it is.
