Why make "tree rings"? you ask. As part of a landscape, a tree is a very special plant and to give it a more formal air and enhance it's place in the garden, a tree ring adds that touch of formality and "class" to the scene. In addition, with this method, I am able to "label" the ring, or add personal touches and or tree names. It's a fun project and I plan on making at least a few more for other trees I have or will obtain.
