I make this Junk Mail art journal this fall. The cover is made of chipboard cut to the size of the largest piece of junk mail. I covered it with torn strips of an old map and then painted it. I added lettering from a Dyan Reaveley stencil. The letters are chipboard and acrylic from my stash. The acrylics are covered with alcohol ink and the chipboard are covered with distress paint.
I started by applying a coat of gesso to everything. I get an enormous amount of junk mail. It only took me a couple of days to collect more than enough.
Once I had all the pages covered as I liked, I bound them together using my Cinch Bindery machine.
