This is my #1 hobby.
Second: Leatherwork. Something I got into in my early teens. 'Tandy Leather' is the place for this. I have a rather extensive set of leather stamps, tools, stains and paint for that. I've made wallets, belts, checkbook covers, rifle slings, a few purses, cell phone cases. I have a stash of kits for this hobby too! A few holsters, cartridge cases, drink holders, etc. I discovered using my airbrush for this. No mixing or thinning required! The results last forever. Far better quality than what you could buy buy at a store. The wallet I use was made over 10 years ago and it still looks almost new. You get to pick your own pattern, color schemes, etc. I should make a luftwaffe wallet, complete with a yellow outline and mottling. Actually, that might be pretty cool!
Third: Woodwork: Not done too much. I don't have the lathes, routers, table saw, bandsaws, etc. I get pre-fab kits from a place called american unfinished furtniture. It's cheating, I know. Same thing as leatherwork though. It's 'real' wood (birch or alder). Not compressed particleboard stuff that most furniture stores carry anymore. The kits only need light sanding. Then, I stain, clear coat and assemble. Lot's of colors and shades to choose from. I made a few bookcases, my entertainment set and a few other things. I have plans to make a 12 shelf, 8 foot high display case/book case to display my models.
Other than that. Fishing, Hunting (duck and deer) mostly in North Carolina, bike, hiking, and camping sporadically.
