I have attached a pdf that Bill Stevens sent me a few years ago(i thought i had lost it)
Bill used to teach classes in the usa on how to make them
its worth looking at as they really are beautiful to use
i have been testing out different paints/adhesives to use over the last few years as people that sell it (donjer) are unable to send the adhesive
the best i have found is "white knight epoxy enamel)
check out the attached file !
