N.G.
Most of the stuff goes in the trash. Unless it's a really good piece of art that I feel I need to keep, all of the daily work/drawings go in the trash. When I want to keep something, I toss it in a box in my daughter's closet. The informational stuff, I have a magnet clip in the kitchen that I keep that in. That way, I am continuously reminded about important dates, etc., whenever I walk by it. It has really worked, I never really forget due dates, order forms, etc.
