B.S.
I seen on pinterest that people spray the dollar bill with glitter spray. I thought that was cute. I also did see the tiny notes that come with the money those were cute too.
For me....I didn't do anything but put money under their pillow.
Also, if I had a do-over with my kids I would get or make a tooth fairy pillow that hangs on the door because its a pain sometimes trying to find the tooth under their pillow.
