In my previous home I had a blank wall in my kitchen next to the kitchen table. Using two curtain rods and clip rings I would hang my children's artwork. I don't have a clear shot of it so I'll share some pictures I found online of the same idea. It was a great solution without having to plaster the fridge with artwork. I cleaned it out pretty regularly to not clutter up the space. I know the idea was copied in many other homes!
