I have turned lots of willow. In our high school Ind. Arts class we had a good supply of willow. I have made bowls out of it with no problems. The best thing we did with it was to make base ball bats out of it! Light but they felt good hitting both softball and base balls with them. We were told that you could not use willow bats in professional baseball, supposedly they flexed more and gave extra distance to a ball hit with a willow bat. May have been malarkey but we made a bunch of bats out of willow, everybody wanted one!
I never thought the wood was very pretty, just plain straight grain. Other than the appeal for bats the only thing it had going for it was the low price compared to the other wood we had in the shop. If I remember correctly we paid about .40 a board foot for it.
