My kids draw pictures and make things for me ALL THE TIME. And they expect me to save and treasure every single one. I do treasure them, but I don't have the inclination (or space) to store all of those papers and things.
The solution is simple: take pictures!!
Star Wars is a big theme around here. My 7-year-old son drew these:
In case you missed some of those details, here's Princess Leia. See the buns?
And here's Yoda. I love the frownie faces. And the stick legs with ball feet.
He's not alone in his Star Wars fixation. My 4-year-old son did this one of Darth Maul. He was so proud of how he turned out. Fierce.
He also did these of Yoda. Star Wars art is so simple, no bodies required!
My 5-year-old daughter did this one of my husband. The body is included, but no clothes.
I typically like to label the artwork with the child's name and age, though you can tell by those above that I often forget.
Some things the kids want to keep on paper, not just the computer. They typically do those things into composition books. My seven-year-old son is currently writing his own reptile book, complete with drawings. =) My nine-year-old daughter is currently writing her own comic book, again in a composition book:
You can also do pictures of things they build, paint, etc. It all stores nicely on a computer, disc, etc.
How do you store your kids' projects?
