We also do the memory boexs. ....had to start doing that when my 3rd daughter started preK and i realized i had all of my older kids work from PreK on up through 4th and 6th grade. i went through and kept things like journals, stories and let them decided on art work to keep....after that, the 4 boxes became one for each kid.
we also began framing their artwork. not all of it mind you, but i have a few dozen pictures framed that are around the house and one wall in the living room that is soley the kids artwork.
ive also decided to take a huge old window and make that into a frame to hold 12 more pieces of art.
my kids love that they can see their masterpieces and we get tons of compliments on them.
