I discovered this by accident, actually, when I was trying to add a little "oomph" to old-fashioned alphabet letters by chalking around them. When one accidentally came off, I discovered how cool it looked! So I promptly removed them all and loved the look. I do this often on purpose now and have used up a LOT of my outdated alphabet stickers this way that I wouldn't have used otherwise! For an even newer look, I sometimes mix up letters from several different types of fonts! :)
