paintingfriends.com, Cindi shared a recipe for keeping watercolor paints moist. Well, I had all the ingredients and was going to mix an 8 oz. bottle. Silly me, I kept getting mixed up on the measurements and ended up with part of a 2-litre bottle full and not sure whether the mixture is even correct except it does contain oxgall, glycerin, gum arabic and water. Will see how well the paints retain their moisture. I especially wanted this for quin. gold and quin. burnt orange since they dry rather flaky. Hopefully, this will resolve that issue. Will have to see if the paints dry well on the paper though.
