For me, the most challenging aspect of letterboxing is the carving of creative and beautiful rubber stamps. My wife, puppy and I use unusual factory made stamps still, and, so far, have been negligent in our duties as devoted letterboxers to carve our own.
I have gotten bits of information from various people, but nothing conclusive. Until now.
On line I stumbled upon a rather eclectic personal web page for a gentleman named Kirby Palm. On this page he has devoted a huge subsection to very practical and well considered advice on how to go about carving rubber stamps! Kirby is a fellow letterboxer, and he has addressed the art of stamp carving to a great extent from the perspective of the letterboxer. He covers hardware, materials, images, how to make a stamp blank, transferring the image to the blank, labeling the stamp and sundry related topics. It is a brilliant contribution to the topic, and I am extremely pleased to find his page!
