About the only hobby I have these days is writing, though I still have outside interests, mostly gay charitable, especially with HIV/AIDS.
I've had many hobbies over the years, and I'd pursue some of them at the same time. They included several involving hand woodworking:
- building stringed musical instruments from scratch (interestingly I couldn't play them myself), primarily 3-string mountain dulcimers and 5-string banjos, both indigenous to the US
- making miniatures (aka doll houses), though not for play, strictly for adult display, and mine not houses per se, but period stores, and made some of the tiny furniture for them, too
- building wooden toys for kids, like cars & trucks, spinning tops & whatnot
- making shadow boxes for wall display, my favorite material coming from discarded wooden fruit crates I'd salvage from behind grocery stores, themes including stores like above, and roadside country fruit, vegetable & flower stands, similar to those I remembered as a kid. I'd also make the flowers and pots myself from narrow paper ribbons using another hobby craft called "quilling"
- photography, first in medium format, later 35mm, also doing the darkroom work myself, a hobby that lasted 40 years, my longest, though nowadays I just take digital snapshots, all my Leicas and other professional equipment gone
I've engaged in lots of outdoor activities, too, like camping, motorcycling, fishing, hunting, hiking, long-distance bicycling, and interests like theatre, music & movies, but I don't really view them as hobbies. I've always felt that to be a hobby there needs to be a personal craft or collector element involved, though others may disagree with that definition.
