Hey on those keycaps you can get, what do you do to the blank one to customize it?

You can do anything your imagination can come up with to the blank keycap to customize it. The blank cap is included with those sets because some people want artwork on a key that we don't make. Basically the idea is to make your own picture on the blank keycap. You can probably use permanent marker, paint, or anything else you can come up with to lay on top of the white area so that light doesn't shine through anything but your custom drawn picture. Or if you don't mind having the light not come through you can put a sticker on it. Just some thoughts...if you get creative and would like to share your work please post it under the 'Mods' section - we would love to see it!
