I think that I will be able to hang my small mounts under my very large ficus in a southern window. When looking around my husbands shop I found some teak and white cedar. I am a little leery of cedar as I am allergic to cedar. The teak will work for a small plant as it is a small piece. I am still want to try the birch bark. It is very solid. I will take some pictures of the bark pieces I found after I clean them.
