Mr. Catboat (or anyone else who knows)-
I wonder about the "cockle" finish used on some of the onionskin papers, supposedly to make them easier to erase on. Is this indicative of more abrasives, or is it just a particular texture the paper has? The specific paper I am using is Southworth 9 lb. onionskin, 100% cotton, cockle finish.
Thanks very much, take care!
