This is a piece of layered white birch bark with naturally grown lichens found on my North Central Wisconsin land. The size is approximately 21 inches long by 8 inches wide. This large white birch bark piece is perfect for painting, writing, or other craft projects. It would make a great hieroglyphs writing material that the even the Egyptians would love. This piece can also look great in a large terrarium vivarium or garden. It was naturally grown and found in my woods in north central Wisconsin and gathered from downed birch trees.
