Like everyone else I'm buried in tupperware. My husband has a set, I have a set, and we got third completely different set for our wedding. Then I bought tupperwares that I thought would be good for homemade ice cream but they didn't work well. Now I have a drawer of much more tupperware than I could ever use.
Repurposing tupperware (and not replacing it) is a great way to empty out your tupperware drawer and get more organized at the same time!
You can use tupperware for storing food of course. I keep some of my dry food staples in my old set.
Don't forget that things other than food store very nicely in tupperware. Add in a label maker, or make your own labels and voila! Instantly organized sock drawer. For this I used all of the tupperwares I bought to use for homemade ice cream. This only took me a few minutes to set up this weekend and it's already saving me time in the morning.
You could use tupperware to store your makeup, batteries, small tools, or sewing items. What other items could you store in tupperware? Or do you already do this?
