Re: [ATM] Persistent turned-up-edge in mirror
Ken,
Thanks for your novel suggestion.
What is the function of the cheese cloth, and what should the result be
(that is, how would I know whether it looks right the next day)? (Is it to
put some structure into the pitch?)
Do you think my fairly hard pitch (a mixture of about 50% 64 and 50% 73F
pitch) is right for this approach?
Thanks,
Bernie
