The wife tried her hand at some abstract painting and sent me some images of her work, which she has since destroyed. I'm not generally one to criticize, but using the dryer (which we use on a regular basis for laundry) seems a little impractical, and employing an entire load of blue jeans to apply the ink to the inside of the dryer also seems extravagant. If the effect here appeals to you, though, it's a relatively simple procedure to try for similar effects, though your results will vary. You'll need a dryer, several pairs of blue jeans (the wife used a mix of work and good jeans, but work jeans will probably work fine, and cleanup is easier), and a good, full rollerball pen. The wife used a brand new one the dentist gave me for Christmas. (It's best to ask, or use your own).
As a side benefit, when you do decide to edit or erase the painting you've created, the fingernail polish remover generates some powerful mind-altering effects when you apply it in the dryer drum and put your head in.
If you want more tips, contact her directly. I don't care to relate the questions; she seems a little touchy about the procedure.
