Keeping the key to my sweet home cozy.
This is inspired by a few key covers I saw on Japanese websites. There was one site in particular (mentioned below) that I based mine on. Although mine is pretty different than that one too. I used felt and made it in the shape of a tag. And I used ribbon instead of a cord (because I didn't have any cord on hand). And I embroidered a bit of pink tulle in the shape of a heart onto it.
I don't know how the Japanese use these, but this could be worn as a "necklace" or around your wrist, or loop around your purse handles...or just toss in your bag.
(I decided to turn this into a tutorial...I'll post images to go along with it soon.)
