Your coat of arms can be etched:
E-mail me a .gif or .jpg graphic file (as an attachment) of your coat of arms, I'll get back to you with the cost involved.
Because of the method of sand etching glass, I must use a new resist with each etched piece. It is impossible to remove and reuse a hand cut vinyl resist, or a photoresist because the vinyl is cut in place on the glass, and the photoresist is glued onto the glass - both are ruined during removal.
