My fridge cannot possible hold the amount of art work that my children wish it would, and I do love for my children to be able to display art work that they are proud of where everyone can see it. So, while I was at the Dollar Store, I bought 4 regular clipboards. I used regular $.99 acrylic paints that I already hand to paint the clipboards brown and black. Then I hung them above their little table (which we keep in the kitchen area). They love being able to display art work on these. The handprint picture has been there for probably 2 months! And, no, they are not actually hung crooked, I just took a bad picture.
Super easy, frugal, and fun for the kids to display their "proud" pieces!
