Dealing with kids' artwork

Schools in and the artwork is rolling in. To be honest, the girls create more art than I know what to do with and I have a strong anti-clutter gene. To deal with their artwork, I sort every piece that comes into the house into 3 categories:

  • Keep: This is the art that I want to keep for years. There has to be something very special about it. I organize this art similar to how I organize the girls' paperwork. Each girl has a 4 inch binder with 50 plastic sheet protectors in it. By my calculations, that's 2-4 special art pieces per school year. So far they each have 3 pieces in there including a foot-print art (so they can look back and see how tiny their feet used to be) and first drawing of the whole family.

  • Display: This is the nice art that gets to be displayed for a while before it's "retired". It includes mother's day gifts displayed on the TV stand and the art I display on the kitchen wall. I remove them when I have another nice piece to replace them with. The kitchen wall display is space limited to maximum 4 pieces per kid. The girls love seeing their art displayed in this form. I must confess that all the Mothers' Day crafts I get from the girls fall into this category and none have been taken down yet because I'm emotionally attached to those and I may end up having a mommy memory box for these when they become too many to display!

  • Retire: This is the art work that gets retired into the recycling box that's euphemism for trashed! A lot of pieces go into immediate retirement.
What's your approach to kids' artwork. Do you attach a sentimental value to them and keep everything or do you keep some and lose some?
