You'd think this question would be one of the stickies in this sub-forum, but maybe it is, but I couldn't find it. :confused: Where do you guys usually procure mylar sheets that will protect the negative from humidity based processes like ziatype? I assume in this day and age, online places would be preferred. I found one vendor that kinda matches the product names, but not sure about the thickness. Any customer's story here? Extra info on what kind to look for, thickness, etc. would also be appreciated.
