I'm hosting a swap on atcsforall.com, the Recycled Artist Trading Card Challenge. I've included a list of various recycled type items and the requirement is to use at least three different items from the list on your ATC. These are some of the samples...
This ATC uses a 1) security envelope liner as background, 2) vintage text, 3) paper napkin and 4) old sheet music.
This card also has a 1) tissue box background, 2) foreign text, 3) used postage stamps, 4) part of an old asian envelope and washi tape.
This one has a 1) vintage dictionary page text as background, 2) used postage stamps and 3) bit of an old ticket and washi tape.
