Want to make a "permanent" valentine? One that will last for years and forever be a reminder of the bond you have for one another? With this instructable, a few tools, some concrete mix and a little work, you can do just that. Easy to do, this stepping stone size heart with names should last for many many years. A mold is made for the heart itself, letters are cut out of styrofoam packing material on a hotwire instrument, and cement is mixed and poured into the mold, around the letters.
