At least I think this is round 14... In either case, I'd started using corn starch as a size and that's working pretty well. I've also replaced the sponge with a rolling pin to squeeze the water from the pulp. It's a bit messier and there's a certain knack I'm still working on, but it's vastly faster and produces a better, more burnished sheet in the end. Round 15 was made with just printer paper pulp but I'm still waiting for the sheets to dry so I'm not sure how that's come out yet.
