Quoted from kwietsch:i think i can make some overlays in two weeks.
how many people are interested?
Just print a bunch and make them available on ebay or sell the lot to a distributor to make available. The reality is, people don't need it till they have a game that needs it; so your orders will be sporadic.
That said, I think there would be need for the lower PF as well. Perhaps you could sell as a set?
