I love all the reuse ideas. But this only works if you don't have someone who throws things out when your back is turned. We drink coffee in the plastic containers or in bags. So when I got 2 coffee cans I stuck them back. My brothers step daughter tossed them. She doesn't understand saving Anything to reuse. I have tried to explain to her but it just doesn't get through. She of course has no hobbies at all. Maybe that's it.If it isn't used within 24 hours out it goes. ACK!!!
