This year I added a skeleton (full size) who is "walking" his three large spiders on a leash (I saw this on pinterest). Looks great during the day time. I used my "glowing" skeleton (from home depot) so at night I put a blue or UV spotlight on him and he shines a bright ghostly yellow. The problem is how to get the spiders to glow. They are 1) grey, 2) dark purple and 3) black with red stripes on the legs. Any lighting suggestions? Or has anyone used those "invisible" UV paints? I tried a regular fluorescing paint, but it completely changes the color of the spider and makes it less visible in the daytime.
