I have been saving wine corks from Mr. P's wine for years and have quite a lot of corks. I have a Pinterest Board for what to do with wine corks too. When I saw several key rings made using wine corks, I thought I can do that! So I made myself a key ring. I made several more key rings, but haven't photographed them yet. I will try and sell those and see if they will sell. I will have several on hand gifts ready to give too. Since it's cork, it will float, unless there are too many heavy keys weighing it down, lol!!!
A few keys and plastic stuff like library cards, loyalty cards.
