If there’s one thing to spend your money on, it’s an Etsy shop. Think of all the irreplaceable trinkets you can purchase at an Etsy store that are gosh darn priceless. For instance, you could get a balloon with an animal drawn on it. Or you could get a balloon with another animal drawn on it. OR you could get a balloon with a person drawn on it. That sounds like a perfectly good thing to spend your money on.
Check out this awesome Etsy shop made by the Mary Sisters. It will definitely be money well spent.
