My kids have a ton of artwork. They do art projects here at home. They do art projects at the library. C does art projects at school. I found a way that works for great for us to showcase some of their artwork without crowding the whole house - we hang it on the kitchen cabinets.
We only hang our favorite projects. When the cabinets get full, we pick what gets replaced with the new projects. I know what the boys favorites are and I make sure not to replace them. (The feather and the charts are months old, the fish is new) This works well for us!
