I've made boards from a few paulownia logs. The lumber is super soft, palish white, straight grained, has very wide growth rings and is non attractive. Fresh sawed paulownia smells a like waste matter discharged from the bowels of a pig. It stinks bad, real bad, enough so that you'll want to put on a gag bag when sawing it. I stacked the paulownia lumber I sawed and tried to sell it, no one wanted it so it sat there till PPB and termites discovered it was good to munch on. I ended up tossing the entire stack into the burn pit, it was a big waste of time. Honestly I can't see how a person could use paulownia to build furniture, it's to soft for construction, it may be good for pulp wood or it may have some tonal qualities for stringed instruments?
