Now you lost me.

You have done work for 33 people (not including business card, cardroom, wedding chips or home poker sets)

of those 33 you have done work on collectible clay casino chips for 18 people.

so what did you do for the other 15?

(BTW as an aside. . . as I have stated before, I have not made up my mind that repairing chips is a bad thing . . . I'm still undecided on this issue)
