The second underquilt is complete and my wife is out back testing it out right now. This one has three layers of Climashield and she feels no cool spots so it must be working. We now have identical setups with the exception of the insulation and are ready for a weekend out soon. I actually used my "new" sewing machine to make this one, an old Kenmore that I worked over and it is running like new. I want to thank all of the DIYers for giving me information and motivation for trying this new method of camping. Hope I can repay the effort some day.
