Use the attached file, and update the number (or delete it, if you want). You can add year, or town/street name, or a name to it.

Also you can change to engrave it instead of scoring - I like how the paint pops up.

With acrylic markers, it's easy to paint the windows and the hearts. Also the number (or text) can be painted out. I am using Posca fine point markers to it.

With a few minutes to dry.

To make it last longer, add varnish to both sides and aside. (Do not forget the inside of the ring, where you'll put the keyholder).

Add the ring to it, and you can use any other embellishments to personalize :)

Share your version, if you made it :)
