No experience with willow myself but I've seen some lovely examples of peeled willow walking sticks right here. As for seasoning. The stick may have been there for awhile and I've always found the year plus to be more of a guideline. I usually only go a few months if I harvest in late fall or winter. And remember, a found stick is going to have less moisture than one just cut. But on the other hand... We are in near drought conditions in my area so I believe a cut stick in that condition will take a lot less time compared to one in a wet season, but I may be wrong about that. Anyway I'm rambling. Nice sticks!
