To make some yourself, all you need is some baking clay and an oven! Start with a block of premo clay. I used glow in the dark cause it looked the most like tooth color and well, yes, I like that they can glow in the dark!
I've never worked with premo before but those of you who have probably know that it's sectioned off in little rectangles. I only used one rectangle for this project and ended up with about 24 fangs. You can see in the pic below that I had a store-bought vampire fang to use as a model for size (although mine ended up looking nothing like that). I basically just broke off little balls, rolled them around between my hands to warm the clay up and make it pliable. Then I just shaped them into fangs. I tried to make the tops have roots like human teeth, but my husband told me they were looking too much like shark teeth. So I ended up squishing those down and etching some lines in the top with my fingernails.
I had found this awesome old jewelry box for $5 at an antique store a month ago. So I lined them up in there with a little bottle of "holy water" ($1 glass vial from Joanne's) and a cool gothic cross I had from an old Halloween costume.
Super easy, super cheap and it will fit perfectly in any vampire hunter's home!
