I have had this stamp on my To Do List for a long time, and I finally carved it about a month ago. I had a heck of a time getting a good image with it, though. I even bought new stamp pads and everything. With the help of 3 Blind Mice, I've arrived at the conclusion that the iron-on method affects the way the rubber (PZ Orange) takes ink. It's not noticable at all when the stamp is negative, but when the stamp has lots of positive area, you can see the splotchiness. (I hope I have my positives and negatives straight there.) I've had it happen recently with 5 of my stamps, and I never had this problem before I started using the iron on method.
