I'm bored a lot too. There is so little to do in my town -- at least of the kind of thing I'd enjoy. And of course some things are shut down because of Covid. I tried initiating a couple of things, but there wasn't enough interest.
I already speak some Spanish, and I found an online language exchange app. I have one language partner in another country. We speak Spanish for 10 minutes and English for 10 minutes, 5 times a week. Your husband might enjoy having a long-distance buddy with a shared interest. Apps like Telegram are free.
English is very much in demand on the language exchange app. I can't help everyone personally, so I host a trivia game twice a week. It takes me several hours a week to look up new questions. I'm a trivia fan, and doing it for others adds a whole new dimension. Plus, people appreciate it, which feels good.
I like
@Mike 's suggestion of building a solar system too. Not that your husband would necessarily be interested in Spanish or trivia or astronomy. But is there something that he's already interested in, that he could parlay into a structured activity, something with a goal? Instead of reading, would he be interested in writing something? For an AA publication perhaps?
It could take some stumbling around at first. If you depend on others, or try to do something for others, they can let you down or not show up, etc.
Personally, I don't like most crafts, and when someone urged me to try coloring books, that hurt my wrist.
Years ago I made piñatas to order, including cartoon characters, Santa Claus, and traditional designs. It was fun.
Selling them was fun too, although not very lucrative. If your husband likes making anything at all (even cupcakes!), he might enjoy selling them at a farmer's market or elsewhere.
I have a friend who goes all out decorating her house for every holiday. She collects decorations, enters house decorating contests, etc. Not my thing, but she gets a lot of satisfaction out of it.
