I forgot to mention that the purpose for using white glue is to keep the ink from absorbing into the paper; if it goes into the paper it won't transfer to the pot. Using water soluble glue allows the paper to be rubbed off while leaving the ink. I spray the pot with a clear mat or flat finish to help protect the image when everything is dry - any outdoor finish should be fine.
Oh, and don't forget to reverse to image when you print it - don't ask how many I did backwards - it's embarrassing! ;-)
