I have a tote that I place papers in that 'look' like something worth keeping. Then at the end of each grading period (for us it's 9 weeks), my daughter and I sit down and choose a few things that she thinks are important (I make her tell me about the project) and then, I place them in clear paper sleeves and put them in a binder. I take pictures of her before each grade and place that in the beginning of the section for that year. If there are VERY SPECIAL paintings that she has done, I put those aside and let her choose one for each grandparent, and let her frame it for them for a gift for christmas! I really think having the binder is something that takes up VERY little space, but is easy to store things in. I do not save andy rinky dink projectes that will not stand up the test of time ~ I have a memory box that is a bit bigger than a box for western boots and that is all she has to put stuff in for elementary school and I have one for middle school and one for high school. Good luck!
