I plan to put bumper stickers on my car.
At MJ designs, and other crafts stores, for a nominal fee, you can purchase a rolled magnetic sheet. It’s called: Adhes.A.Mag.
You stick your bumper sticker to that sheet, and cut out around it. That way, your sticker adheres to the car by magnet. When you’re parking in an “iffy” parking lot or neighborhood, take the bumper stickers off and put them in your trunk.
It’s very easy to do.
Thanks. I will look into that.
