I have a plethora of hobbies - I'm constantly busy.
The most prominent and current ones include: chainmail (mostly jewelry, but a few bigger pieces) & metalworking, photography, going to the gym, skating on my brand new Land Rollers, playing with my seven cats, two sugar gliders, and hedgehog, watching TV (while petting kitties).
Other hobbies that I'm currently less busy with: drawing celtic knots, beading (on a beadloom), stitchery (needlepoint, blackwork, cross-stitch, couchwork, etc...), packing bento lunches (ok, the hobby is really in searching for and procuring new bento boxes and accessories), cooking, gardening, glass etching, woodworking, and .... more.
Like I said, I'm constantly busy, but the critters take a lot of time to keep everybody happy - I just hung two bird feeders outside our big window and put out squirrel chow so that the cats have a hobby too!
