Double up your paper, the outside layer can be not perfect, and smaller than the inside sheet, but make sure your inside sheet is perfectly straight and aligned properly. Always double it up, and make sure there are no weird creases or folds where you don't want them. Don't both with expensive shit, I've tried most of them, and this is what I use now for every single press.
Make your own stay-wet palette!
1) white parchment paper, https://www.amazon.com/dp/B07F6F631N?ref=nb_sb_ss_w_as-reorder-t1_ypp_rep_k0_1_5&amp&crid=3FWP13GCEJTRX&amp&sprefix=parch
2) paper towel
3) any old plastic container with lid - I use the ones from chinese food and Mejdool dates. The reason I don't use tupperware, say, is because sooner or later they WILL mold.
Cut or fold the paper towel to fit the container. soak it with water, pour out any excess. Cut the parchment to fit on top. Press down with your fingers to get a tight seal against the paper towel. If the parchment curls, tape it down.
-place your paint on the parchment. As long as the paper towel is damp and the lid is on, the paint will stay wet.
-as a bonus, the parchment paper is good to have around. If you just want the paint to stay usable for a few hours, you can use any flat surface, a wet paper towel, and the parchment to create as large of a palette as you want.
well for me, the 12" wide from reynolds was a better fit for my press frame, but the norpro was so wide i could rip it in half and use both halves, it really depends on the setup, some have 3x3 plates, so small pieces, mine are 3x5, but some have 4x7 +.... just a matter of length, we use a lot so bigger rolls would work well imho
