We've all seen loads of the hook/shelf/shoe cubby organizational situation. And differing variations on the same theme.
But this looks both smart AND classy. Hang as many hooks as you have backpacks. Use 4 same size frames (pop out the glass and add corkboard...) and paint a unifying color. Initial for each persons spot. Sign me up; I'm doing this before my brood goes back to school! Great idea.
