Design is a very important part of my puzzlemaking, and the Rubber Stamp puzzles are no exception. While they are simple in terms of their design, it took me a while to get the right font for the numbers, the right colors for the stamps, and clean lines for the puzzle itself. Everything that you see when you get the finished product was a choice along the way. In trying to present a clean and simple interface for the puzzle, I rejected a lot of things that could be associated with rubber stamps, such as a textured stamp imprint (with the imperfections that you'd get with a real rubber stamp), or textured "paper".
