These are two pieces of white birch bark found on my North Central Wisconsin land. The size is between approximately 9 and 17 inches long by 4 and 5 inches wide. These various white birch bark pieces are perfect for painting, writing, or even building a miniature birch bark canoe. They are 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. They were naturally grown and found in my woods in north central Wisconsin and gathered from downed birch trees.
