I can answer that...
The minimum seven interested members would have to order a minimum of 100 pieces each for a total minimum order of 700 pieces.
One side will feature a common CPMF design. All pieces from all members participating in this order will feature this design on one side (let's call this the reverse). The other side (the obverse) is a blank slate for each participating member to choose their own design. You can choose from a variety of pre-made dies, or you can design your own obverse.
As seen in the proposed CPMF reverse above, the tokens themselves are 1-3/4" in diameter. The area available for the design is 1-1/2" in diameter. Your entire design must be contained within this boundary.
As would be the case if you were to design a coin, work with a sheet of paper (or space on your computer screen) about the size of a dessert plate (about 8" in diameter) and sketch out your ideas. Once you've got a design you like, reduce it down to 1-1/2" in size and see how it looks. You will want to stick to simple designs because if two lines are too close together, you might run into a problem where some of the coloured foil just fills in the gap. (I had this happen on a moderate number of my tokens on letters like a capital A... the core in the top part occasionally got filled in because the space was too small).
Feel free to post your designs-in-progress to this thread so you can solicit feedback or get ideas from other members.
We're also looking for suggestions for the reverse image. The one above is admittedly a little too complex and probably won't turn out so well. The fine detail will probably be a little too much and it will all run together.
Also just a note... the image is applied to the token with a hot magnesium die and coloured metallic foil. No ink is used. The foil is effectively melted into the wood without any burning or other undesirable blemishes. The finished products are really attractive. You might also get the attention of the Canadian Association of Wooden Money Collectors (CAWMC). They're a fun group of folks who just go nuts over these little pieces of wood!
