Guess i'm the first to say it, sewing. Not necessarily making things from scratch but just fixing what you got and adding features. Fairly affordable hobby, easy to get into and plenty of tutorials.
I learned sewing as a way to bond with my mum, who is a sewist. Im a 35 year old man for context.
I bought an old 2nd hand machine, fixed it after realizing it was broken, and started sewing for under $300
I learned how to make hats and stuff. Now we spend weekends upcycling fabrics from the thrift store into handbags, hats, toolkits, all sorts of things. She wants to start an etsy store, but only after we have made a few hundred items to photograph and list
