I absolutely love being able to use vintage fishing products in my creations. The base of these driftwood trees are made with the old cedar lathe turned corks used in the gill net fishery around the 1940's and 50's. For a brief time they were produced commercially in Astoria Oregon which is also an original Finnish settlement like Sointula. I use a single piece of Aluminum tig rod to create the sea star shape and run it through the driftwood and then screw it to the bottom.
The aluminum won't rust just oxidize a little over time and be less shiny. It is safe to put outside in that regard.
This tree measures 14 inches high or 36 cm.
