I used hot glue to "draw" the dimensional spiderweb on the side and painted over it with a black gesso wash. When that dried I dry brushed the web with white gesso. All splatters are either orange acrylic paint, black gesso wash, or white Dylusions spray. I just slung it off the brush (and also splattered my pocketbook ... sigh).
Here's what the BEFORE looked like after I attached the Tussie Mussie (it was also made from a scrap piece of chipboard). I used a craft knife to cut out the inset where I would place the moss and tea light. The switch to the tea light is easily accessible in the bottom of the hat.
The hat is approximately 11" tall. Great size for a mantel or table decoration.
