Thanks for providing these. Anyone have something similar for the round call letters used in the teledials?
Follow the same directions as above to create the text on the background.
Purchase a round gasket (leather) punch, like those made by General Tool and others, better the quality the cleaner it will punch and can be re-sharpened. Place the printed sheet on a surface that is somewhat compressible like the end grain of maple block. Place the label on the block, punch on the label and firmly whack the punch with a suitable hammer, repeat as needed. A clear plastic liner can be made from a suitable bottle plastic. Certainly, it will take some practice to get.
