I have it! Mylar balloons. The ones they blow up at parties?
Un-inflated mylar.

I got several from the 99 cent store, so of course they were 99 cents
each. I got the solid black 12 inch diameter ones.

I threw them in with a load of laundry, plus bleach, then into the
dryer. The came out wrinkled but fine.

A couple of notes for sewing though... don't iron them. Big problem for
the iron. Fit them inside your two fabrics while they are still smooth.
Much easier to work with. They are no harder to sew than say silk or
satin, a pain, but doable.

Thanks to everyone who sent me suggestions. It was some of those
suggestions that got me thinking outside the hammocks and sleep sacks,
errrr I mean box!
