My Uncle cut down and old tree and a couple of the logs had some areas that birds had made homes in.

I attached some scrap pieces of wood to keep the logs in place.
One of the logs had an area where the hole went all the way through. So I stuffed some burlap fabric in that area to prevent an soil from falling through.
Added some soil and flowers and that's it! Look how cute these are!
