I just read this idea...so I am not taking credit...but I LOVE IT! When you buy a new pair of shoes, keep the box! Take a photo of the shoes and glue/tape it to the outside of the box. Then when your shoes are stored in your closet, you know what pair is in what box!
In the past, I have always thrown away the box because I couldn't see what was inside it. Yet, I really need the box for many of my shoes that I rarely wear...the dust builds up on them otherwise.
Isn't this idea simple and cheap! I think I will start it in my own closet!
