Diamond willow was used and just a fun loving guy. Hang these little guys on any wall. Found this poem a few years ago. Kind of nice for the wood spirit.

The Legend
As you walk through the forest with trees overhead,
You can feel his presence, or so it's been said.
His eyes are upon you as you stroll through the trees,
He is the Wood spirit who hides in the leaves.
The forest is home to Wood spirit a plenty,
His sightings are few, but his numbers are many.
A walk through the forest...a glance at a branch.
He is the caretaker of all that he sees.
If you enter the forest with intentions of evil.
A Wood spirit’s wrath can cause an upheaval.
Though his face is hidden beneath the bark,
A nimble knife can release his true heart.
Can hair be a feather? Can beards be leaves?
A Wood spirit lives for those who believe.
Is it man or beast? Is it woman or bird?
The Spirit of the Woods wears the face of old.
Though his numbers are many, his sightings are few.
A Wood spirits presence can bring luck to you.
