Hi ken, you could turn them to about 1" thick wrap them up in newspaper for a few months then return to finish, helps to dry them out quicker and have enough left on them to turn any movment of warp. You could also look into microwave drying i have had some that have been okay, some not so. Mitch turns green wood and then seals the finish with Shelac never done it that way myself but i think his are okay not heard anything to say not. Me i would go for the turning to about the 1" and then storing for a few months. If its not great wood then try different methods, learn by mistakes trial and erro.....LB..
