I have been making papers to use in collage. I especially like using old copy paper that has been printed on - old emails or documents that are no longer needed. Junk mail, magazines. These all go into one pile in the wet studio and these are the base for further painting and printing and mark making. Once I have a batch of them - they go into file folders according to color or type and these are filed in a filing cabinet drawer.
When it comes time for some "one of a kind" papers - I have lots to pick from. I find I like working with my own papers far better than using magazine pages.
