Before I made it into a shrine box, it was a little hanging cabinet with see through doors. It was originally a v. dark wood. I am constantly picking up little shelves and cabinets like that at my favorite thrift store.
I also have a hoard of little religious statues from the thrift store. I spray painted the cabinet gold and then painted the inside sky blue. I put the metallic blue paper on the insides of the doors so you couldn't see through them any more. I had some small canvases that fit just perfectly inside the doors and used those for Saint Lucy and the Nino d'Atocha. Then I glued the drawers in at that angle so you could read them.
I love shrines too, and the first ones I made were in Altoids tins. I felt better starting smaller. And picking a theme helps me filter what objects and images I'll use. I named my shrine (How Far, Heaven?) to give myself a concept to work with beyond just "religious box." I added the leopard print, stars and glitter to make it especially my own.
for sharing so much! I have hoarded a few containers that I think would be good for shrines and I guess if I think I can come up with an appropriate theme, I could start. I think I'm afraid of ruining something cool, so maybe something like an Altoid tin would be a good start. Or a cereal box.
