This experiment out of Surface Treatment Workshop is very similar to my own experiments with metal tape. The twist on this is that you glue objects down on your base prior to putting the foil over it. In this case I glued a few centavos to an illustration board sprayed it with adhesive and then put the foil over it. The difference with aluminum foil and metal tape is the ability to really wrinkle and manipulate the foil. The wrinkle "veins" create a nice and interesting effect, especially when alcohol inks are dripped over it.
