I heard about this on Deviantart.com and wanted to try it myself. All you have to do is file the fake nails to the desired shape and then use the paste to apply them. The denture paste was a little difficult at first, so experiment. Also, check what color the denture paste is IN THE STORE. The color will show through the fangs, and you don't want to end up with green teeth! ^^ Tips: be patient with the paste. Like I said, it takes some getting used to. And you can drink, but don't eat anything. Getting them off is easy.
