My wife is 'addicted' to Altoids. We have hundreds of empty cans and have already recycled thousands. I was thinking I could put them to good use at home. Looking for ideas.
If she is addicted to them, there are recipes online for DIY Altoids. They could be kept in the tins you have. That would also prevent you from accumulating more tins.
As others have said, there are a lot of projects online utilizing the tins. Either you could make the projects, or find a vendor on Etsy or the like that would be interested in lot quantities of Altoid tins.
