I had been looking for a new way to store my computers that I got from Donors Choose (the lovely pink one was my donation, the girls always want that one!). I had inherited several of these wonderful wooden organizers from my mother who had retired from teaching and they were the perfect size to fit the netbooks. I found THIS pin last summer and decided to use it to organize the cords.
Each of the computers is numbers, so the students easily know where to put the computer back so that it goes with the correct plug. Below, you can see how the cord fits through the clamp and stays in the proper place.
