UPDATE!!! I'm now beginning to make a few of these for sale on my Etsy shop. The ones for sale are a box that look like a book. This allows for your creativity in what you want to put inside (Halloween candy / a spooky spider etc). I've added a bookmark that includes a handmade stained glass piece, bead and feather and other adornments. The interior is lined with felt and overall it would look amazing amongst your other Halloween decor. Each one is handmade with attention to detail and seriously look even better in person.
Follow this link to take a look:
Basically you get an old book, glue on objects or cut out shapes from cardboard or foam sheets to design the look. Then take a paper towel or napkin and using only a single ply portion of it, you glue it on over the cover, spine and back and on top of all your objects. Then spray paint it all black. Then using a dry brush technique, lightly brush on copper, gold or silver to get the raised areas to really pop! I love how different everyones turned out but how cool they all look together!
