I made these Super Improvers Wall brag tags to try out this year. They are about the size of dog tags. I bought the template from Fifth in the Middle, in case you want to make your own (she also has a video link to show how to make them!)
The clip art corresponds to the cards made by What I Have Learned's SIW cards:
Mine are just a white background due to ink constraints. Let me know if they are useful!!
