Guess I can say I got the idea of putting insulators on this spruce tree at my front doorstep from a large collection I looked at years ago up in Ontario, Canada. The only difference is that Canadian collector used poles set upright in his back yard. Of course I'm not putting my best insulators outside. Just attempting to put out a variety of colors and different CD numbers for visitors to see. I would like to have a few purples added to this outside display. If you have any with large sections of the skirt missing (at least half remaining)and wish to sell or trade for other insulators I have inside my house let me know via email. Thanks.
