Have a quilt that sufficed for warm 3-season usage, but when moving into the colder times it's not a consideration. Thought I would give a try at a cold 3-season quilt. Had a wacky idea pop into my head (happens all the time) so I thought I would pass it by here for reasons why I am on / off base.
What would be the problem with using a reflective foil inside the quilt, in place of the usual down / therma-whatever. I've used these in SAR to get a person warmed up until help arises. I have one that has seen better days for SAR, but might have a use as a quilt liner.
Life should not be a journey to the grave with the intent of arriving safely in a well preserved body, but to skid in broadside, thoroughly used up, worn out, and loudly proclaiming Wow! What a Ride!
