Put their first pair of shoes in a shadowbox and hang in their room. Use velcro on the backs to make them stay. Note to self: Shodowboxes can be found at Michaels. Something to do with all those adorable shoes! Maybe her first dress?
Add silk flowers behind the knob. This would be cute for a little girl's or teen room. A nice surprise for Spring/Easter with a bunny on the tabletop or a sweet surprise. Doesn't have to be permanent and you can remove when the season changes!
