Other than ukuleles (and now guitar), I've had a few hobbies that consumed a substantial portion of my daily activities.
Up until a couple of years ago, I was heavily into West African drumming (djembe, dunun, etc.) and was taking in-person lessons from several African teachers, playing for dance classes, attending festivals/camps, and generally making a lot of fun noise! Once COVID hit, the in-person activities came to a screeching halt. I quickly found that playing a drum by myself is not very satisfying and the drums went back on the shelf (where they still are). As I'm aging, I'm also finding that intense, physical activities (playing djembe for a dance class is a helluva workout!) are becoming less desirable, so it looks like my drumming days are behind me.
A few years back, I got seriously into fountain pen collecting. I have a pretty substantial collection now of both vintage and new fountain pens. I use them every day and still enjoy them, but I'm reducing my collection and selling off most of the vintage pens. I'll keep a few special vintage pens, but for the most part, I'll just keep and use some of the nicer modern pens.
Another acquisition hobby is vintage safety razors and shaving gear. Over the years, I've collected probably 40-50 double- and single-edged safety razors and an equal number of shaving brushes. The brushes have all been personally restored with new bristles and returned to usable condition. I have stopped hunting for new items, though, since I'm running out of room, quality items are getting harder (and more expensive) to find, and I can only use so many! The ones in my collection all get used regularly but I can't see adding any more. The collection will stay but I've got no plans to make it grow.
