Here are two new stamps available for download from MediaFire.com. They were designed by me, and I'm releasing them in the public domain. You can download each one at the links listed below.
Just open in PhotoLine and save to your stamps directory.
The stamps were originally vector/bitmap files made in RealDraw, then exported as transparent PNG files. Here's a screencap and explanation. RealDraw uses an ingenious device called the Push-Back tool to create intersections of closed lines.
