Here is a short tutorial on creating a Glow-in-the-Dark Mantel for Halloween, by mixing some of the things you already own with inexpensive glow-in-the-dark decor items from Target and Dollar Tree.
First off, we do not have a mantel. Our Halloween Party Glow-in-the-Dark room was our bedroom.
However, we do have a desk with a hutch, that effectively created a mantel type of space to work with. I discovered that grey-colored “creepy cloth” glows just slightly under a black light. It perfectly covered the desk and items underneath, once the real lights were out and the glow lights were on.
In daylight: From there I ran experiments – testing items out under the black light. I found quite a few things that are not necessarily “glow-in-the-dark” still work. They may not exactly glow, but they cast back the UV light well. Particularly, the the grey-colored type of foam tombstones from Dollar Tree glow pretty well under the black lights, as do some of the grey colored figurines.
From there, I just collected items from the house that are grey, black, or white – ceramic pots, jars, my own figurines, etc.- and brought them into the room. I ran experiments, testing them out under the black light. I mixed and matched them into the Halloween decor until they added up to really great spooky collection.
