Blueprint Crafts has a cute idea for turning plain white tiles into custom coasters.
I've been obsessed with finding the perfect coasters for our living room for years now so this seems like a great solution. Granted, coasters don't need to match a room perfectly, but what can I say? I'm picky! :)
The best part about this project is that you can get exactly what you want and it doesn't cost much at all. In fact, you could probably even score a few free tiles from your local ceramic store if they have any batch leftovers or old inventory they're looking to unload.
