Arianna,
I have recently started adding to my china collections. My Great-great Aunt just passed ( 94 years old) she had some beautiful Lefton China Hertitage Green and I am slowly finding and picking up the pieces she didn't have. I also have a nice couple sets of Japan hand painted tea cups and saucers.
For us, we try to do a modest/medium priced family vacation each year (2000 for 5 people). This year we are paying for it with our tax return. NICE!! Other than that i spend a little on the chickens. I am also getting into woodworking. So far this year I made two matching Cedar nightstands for the Master Bedroom (cost 100 total). A cubby storage area for the Homeschool room (about 200 dollars) and a Fabric covered Headboard (about 150). I also have plans to make a kids PlayStand but it uses mostly scraps from other projects and will cost about 20.
My DH has started spending his own money on guns.
To help with this issue DH and I have an allowance. We both get 50 bucks a month to spend however we like. So if he wants a 200 gun, he has to save up for it. Same with me.
