I have had a lovely bottle tree in my yard for four years and in my last house I had several bottle trees out in my garden to trap the evil spirits (an African legend) and provide beautiful color to my yard. Now I am on a mission to find small blue bottles to get more color and fun out there. Remember all of those cute little blue bottles people sell at thrift stores? And where are the red and purple bottles? I can't seem to get enough beautiful color in my life.
