I invented something funny here, at least I didn’t copy anyone else, but probably somewhere in the world someone has made carved a pumpkin like this and made the interior fluorescent. The idea came to me after I made a little pumpkin egg sculpture out of polymer clay (found HERE), and then I wondered whether I could make it into an actual pumpkin size carving.
- carve the pumpkin
- scrape the edges really well, and pat dry
- wait until the interior is pretty dry to the touch (I ended up putting this whole big pumpkin in the oven at just over 100 oF for an hour or so.
- Paint the interior with a stain blocking primer (I used water based Kilz) and let that dry for several days.
- Spray paint the interior of the pumpkin with fluorescent yellow spray paint (well I used spray paint, but I think a jar of paint would have been a better idea.
