Thank you all for the good advice. I have about 3 dozen pieces of Batiks and was looking for the easy answer. I guess I will take my time and do it right. Ghostrider, thanks for the pretest idea. That's where I'll start.
I always get confused between Synthrapol and Retayne. I'm going to label the Synthrapol with "suspend in water" and the Retayne with "set" so I can keep them straight.
Many thanks.
