Great suggestions Lori & Barry, thanks!

Lori, for the two quilts, what do you do with the sides of the quilt? I am guessing that you still tie the bottoms to create two foot-boxes?

Barry, I seriously considered the Z-packs dual quilt. It says that it is only 84" at the shoulders and hips compared to 104/90" on the Spoonbill. Granted, all of that is insulated; if a person could rig an under blanket like your current set-up, you would have lots of room. I guess you would need extra length to get it around your head as well.
