This is a piece of layered firm white birch bark found on my North Central Wisconsin land. The size is approximately 18 inches long by 15 inches wide. This large white birch bark piece is perfect for painting, writing, or even building a miniature birch bark canoe. It is thin like paper that 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.
