I have decried elm, attempted several times successfully a couple of times.
I'm with George. I use a LOT of small diameter elm. You need to cut it green and straight from a thicket of other small trees, reduce the stave, get whatever width the diameter let's you, and go with it. I ALWAYS reduce elm to dry, I always spray it with something to chase bugs away, and I ALWAYS restrain it with clamps, atraps, or screws while it dries. Then ignore the crown and use the available width to make design choices.
