Here is the design I created after looking at many existing underquilts.
The details:
3 Season - 20 Degree
3/4 Underquilt
7.0 oz. of 850 FP GD
48"W x 60"L
14 baffles 4 1/4" wide

According to my calculations this would require 6.77 oz of 850 FP down. To make the math easy I rounded up to 7.0 oz and doubled that number to create the number of baffles.
I have two questions for anyone who may have tried this before.
1) Is there an advantage to the baffles being across the long side vs the short side?
2) Would there be any advantage to adding a baffle divider down the middle (long side or dotted line in the diagram) to keep the down more distributed? This doubles the sewing work and baffle weight both of which long term seem to be negilble.
Thanks,
Dave
