I have noticed that some in my quilt groups make a stole and have their names on that instead of a name tag. The put the pins for the various quilting events on them and decorate them however they want.
I made a square in a square for use with one of my groups and a log cabin design with the group's label for the other. I found a vendor where I could buy magnetic badge holders. This way I don't have to pin holes in my clothes.
