From the creator:

The wood in this dock is cherry from the Black Cherry Tree, Prunus serotina Ehrh., which has been prized by woodworkers for centuries due to its beauty and woodworking qualitites. Cherry trees are widespread in the eastern half of the United States and the wood is considered by many to be the premier furniture wood in North America. The leaves in the picture are from a cherry tree. The wood insert is finished with several coats of orange oil and beeswax.

The actual wood used here is from small pieces a cabinet maker gave me about 20 years ago. I knew I would use it one day!

It takes me several hours, a dozen tools and over 30 steps to create these docks. Did I already say they were painstakingly made?
