I made this Make America Nasty Again pin to decorate my hat at upcoming marches. Hope you can get some good use out of it too! Customize with your own colors of Sharpie. If you make a mistake or slip, a q-tip with isopropyl alcohol on it will remove any random marks. Line on back included as a guide for placing a sticky pin on the back.
