This won't work for me....having girls and all, but it IS a totally awesome idea!
Check out Erin's Solving the Shoe Dilemma.
Now, I just need an idea that will work for girls. We have shoes under the kitchen table (2 pair), sometimes we have the one shoe in the bathroom/one shoe in the front hallway mystery Erin was talking about. Most of the time, they can find one shoe where it goes and the mate is a mystery. Really? How did you manage to put one shoe in it's proper place and then....what? You got bored? Distracted?
Anyway, I love it when someone figures out something that works!
