Hi Allen & All, This URL http://www.internode.net/HoneyBee/Spring/images/img005.jpg comes from this URL; http://www.internode.net/HoneyBee/Spring/unwrap.htm I hope you do not mind me posting your url to a picture you have of your insulating pillow? They look very interesting, I have some questions about them and there use. It seems you can put a hive top over them, do they allow for an upper entrance or do you use the holes drilled in the brood chamber? What extra R-value do they provide? I like the way they look and seem easy to make, are there any tips you can give about there construction? I assume the bees glue them down to the top of the hive and seal it for you? . .. c(((([ Keith Malone Chugiak, Alaska USA [log in to unmask] http://takeoff.to/alaskahoney Check out current weather in my area and 5 day forecast; http://www.wx.com/myweather.cfm?ZIP=99654
