Is there a name for the process of using "a blender marker and a little rub" ? I'd like to repeat this on some other games, but I have no idea what you area talking about.
I saw a DIY articles for wooden nickles, but I cannot remember where... I use a Chartpak Blender Marker. You need to print the image to be transferred on a laser printer. An inkjet wont work. also, print the image reversed. lay it over the token, cube, die, etc... print side down and wet the backside with the marker. final step is to burnish it - I would rub with the edge of a wood disk... good luck
