Wanna make one too? You can. It's easy...I promise. If you use leather,** be sure to use a leather needle and a walking foot on your machine. But it would be really cool with thick wool felt too.
Leave you threads long at the beginning and end so you can tie them together to hang.
Then write something sweet (or salty) and leave it for your love to find on their door in the morning.
**Leather stores sell scraps, did you know? So don't feel like leather is out of reach. You can buy small pieces for cheap. And you'll feel like a cowboy.
