Here is what you need:
puffy paint (Make some here https://sugarlemondiys.wordpress.com/2017/03/22/puffy-paint/)
printable outline templates
Trace your designs. It takes is a steady hand and patience.
Simply place a piece of wax paper over the templates, and trace with your puffy paint color of choice.
I left the middle empty, so you can create your own fun designs. Just keep in mind to make sure all of the lines connect and touch each other.
When you traced all of the designs you want, let it dry completely overnight.
The trickiest part is then peeling them off of the wax paper. Peel them away very carefully and slowly.
