Thanks Larry! I've been looking online. I found a place that is a dive shop that does custom patches. I'll just tell them the alcyone symbol is stylized shark.
Their prices seem reasonable. For a 3" patch, it should be under $2 per patch. I would have to order 50 of them, so there would have to be enough people who want to pony up a couple of bucks for a patch. Even if I can sell half right away, I don't mind holding onto the extras so they are avialable for new members.
