I make small items (coasters) that, after finishing them, they sick together. I have tried many finishes and have the same problem with all of them. io have had this same problem with: Lacquer, Polyerathane, Shellac, and Tung oil. I have also waxed them. I have tried placing all kinds of paper between them but they then stick to the paper. I have tried tissue paper, paper towels, waxed paper, printer paper and plastic. Any suggetions on how to avoid this? I have let them dry for about a month!
