While we might love to keep every single craft project we make with our kids, lets face it, we only have so much room on the refrigerator and shelves for their masterpieces. Once a project is complete, take a few photos of it until you have one you like (or scan it in, if it's flat enough), and then proudly display their artwork for awhile. When it comes time to rotate it out (be that recycled, or gifted to other family members), or if it breaks (particularity true with more fragile projects, such as macaroni art, dried leaves, pines cones, etc) you'll have an easy to store remembrance of the work, which can be added to a photo album as a wonderful keep sake.
