I don't know why I have trouble throwing things away sometimes, things that I think I might use in art. For instance, I can never look at coffee grounds or tea bags without wanting to dye some paper.
Last week, it was tea bags. I had made a pitcher of iced tea and had a bunch of tea bags headed to the trash. Somehow, though, my feet took me over to a piece of art paper. I spritzed the paper with water and plopped the tea bags on top of it. I went about my day and checked back later. I moved the bags to another part of the paper and spritzed with water again. I did this a couple more times, moving the bags and checking to see what was happening on the paper. I tried to reposition the bags differently each time--flat side down, bottom down, and also open side down, lightly opening the sides so they sat with a hole in the middle where the bag folded upon itself.
