Eastern Red Cedar is a Juniper- Juniperus Virginiana.
Real Cedar is of genus Cedrus, and are from the Middle East. Western Red Cedar is Thuja Plicata, of a different genus from the Junipers. Juniperus Occidentalis is Western Juniper, but sometimes called Western Red Cedar.
All of them share the aromatic wood though, so...
(I only know this because I have been learning up, I have 30 or so ERC trees in my yard) :D
As for the original post- cut it up and see what you can do with it.
