These are manufactured blanks with routed slots for whiteboard/chalkboard stickers that then get laserbeamed with your design of choice. Technically the process supports grayscale, but I didn't want to risk it.
First, I took photos and scans of my Sithrak pin and Sithrak patch. Then, I traced both with Adobe Illustrator and combined them into a black and white SVG. I then added the circle rings and quotes (making sure to "Trace outlines" of each letter to preserve the font I totally have license to use in this manner). The manufacturers at DesignYourTap.com handled the laser engraving and provided the appropriate chalkboard stickers.
You know how you're supposed to "break in" a new chalk board by rubbing the whole thing with a stick of chalk on its broadside? Don't do that to these stickers, you'll just fuck them up.
One of your beers should be called either Cumsprite (if you have a summer beer with a lemon zesty undertone) or maybe call it I'm Telling.
Only the Oglaffer will get it.
