They were extremely easy and very plain. The snappiest thing about them was the stickles!
On another note, one of my co-workers traded in her car last year and lost her favorite bumper sticker. I finally got around to making her a replacement. I think mine is better since I added the couple and made it out of vinyl. I used Platin Schoolbook and Car Decals. I really like the Car Decals cartridge. It has some really cute images. I have a banner planned that I want to use it for next.
