I have a ton(not literally) of Aspen on my property that has been downed for several years and the question is whether or not it can be turned into a pen? I know that some have called it "punky wood" which I think means its dry rotted from the inside out. If the center is dry rotted but the rest is firm can it be turned. I suspect it would be rather bland looking, but I think it would give me something to learn with. Thanks.
