Being a fairly new hobbiest (3 years), I'am still experimenting with things trying to find what works best for me. So today I took delivery of a few of the plastic tops, inner covers and bottom boards that are sold by the W. T. Kelly Co.. Thinking I would try them out with some packages in a couple of weeks, but now I'am having doubts. After seeing them I began to wonder if they would not provide enough insulation in our S.E. Michigan winters. Which may lead to exessive moisture build-up. Am I being conserned over nothing or is this warrented? Has anyone used or currently using these? With what results? Its entirely possiable that I'am being a bit of a traditionalist and just cant picture my "ladies" walking on anything but "warm" wooden floors. Seen my first dandalions today, can barefoot children be far behind! Tim Damon Ann Arbor, MI, USA [log in to unmask]
