I do! Altoids tins, film canisters, empty lip balm jars, whatever. If it's teeny tiny and has a lid I need to save it -- the tinier and more useless the better. But I'm afraid of becoming hoarder so ever few months or so I throw them all out.
Anyone else have this obsession to collect small containers? What do you put in them?
I know the feeling. I am currently collecting plastic containers from vitamin tablets. They are an unusual shape (because they come through the post and the company has made them tall and thin to go into letterboxes) and I thought they would look good stuck together as a pencil storage space. But they are mounting up and I still haven't glued them! I think your idea of decluttering them every few months is a good one. Must try that before the pile gets much bigger!
I'm not so bad with the small containers, but I have found myself in the past year or so collecting containers to organize myself--organizers, pails, decorative boxes, baskets . . . . I've never even liked baskets! Now, I just need to use them! haha
