Re: Combining Pt/Pd and cyanotype

Hi Marek,
Thank you for responding!
Kerik is having a class at the Formulary in July with Gum on Plat/?Palladium
and I think that I will go(I can travel in my camper to that area). I have
never 'done' the gum so; I have some ideas as to what I want to do...
Have fun,
Susan
