LOL; Wife asked if she could take a sewing machine. Even gave me a Singer featherweight for my birthday. (saw me looking one over while she was in a shop. When asked I said it was cute. Later, when she gave one to me I said I had seen a lot of cute things in tight jeans that never came home with me)
We have set up a little carry-on sized bag that holds her small electronic, or the featherweight, the small iron and pad, modified short heavy duty extension cord, cutting mat and all the other stuff she takes when going to a retreat. Packing this bag when we go camping is a piece of chicken. But we have a popup trailer. For her to sew, we need to take 2 folding tables, a chair, a tarp to set up on so we can clean up all the threads and scraps she cuts off, and sometimes a tent. If we plan to stay someplace for a week or more, I deal with it.
Most trips, the compromise is we travel a day, then camp a day. (She might bring a quilt that needs binding put on) The next day we tour quilt/fabric stores. Camp a day, then a travel day. The shop/camp sometimes get mixed. Hot weather, camp mornings, shop afternoon. If (if? no when) she finds a pattern and fabric she will sometimes put mat and rulers on picnic table. If she gets much stuff, we might have a issue keeping it clean and dry for the rest of trip we stop at a post office, mail it home.
