What do you do with your Park Badges?

We're starting to amass a nice little collection of park badges, but we're not sure how to present them. Somehow hang them on our wall? Sew them to a few backpacks?  Let us know how you collect and present them, we're looking for creative ways to share with our readers!

Thanks to Katelyn for letting us share her handiwork of this great patch blanket (looks like lots of room for a few other places to visit too!)...
