This is something that I have been wanting to do for ages and it is rusting paper and metal bits. I purchased a heap of the star locking washers and other metal things and rusted them with a vinegar mix. What amazing effects, it really works. I then tried paper, wow what fun to be had. I am amazed at what has been achieved, even lace can be rusted. I can't stop rusting things now and yes I am using the rusty items on work. Here you can see all the ATC's are made out of rusted paper and rusted metal bits.
