In a small window of time in the early spring when the sap is running, Mark Greene of Black Mountain goes into the wood and strips the bark off fallen trees. It is the only time of year when it is possible to get the bark, so he does what he can at that time, and whatever he manages to forage, he makes into bark baskets. Mark knows how to cut the bark and dry it in such a way that the edges curl into the center. No glue or nails are used. The baskets are suspended from rawhide strips. Each one bears a handmade acorn fashioned by the wife of the basket maker. She is a fiber artist who knits socks for us. No two are alike.
