I bought some material a week of so ago with the idea to try making an insulated window blanket. At the fabric store I found some brownish-red microsuede material that was deeply discounted, and some
“Insulbrite” sorry, “insulshine”. foil faced polyester batting material (about 1/8″ thick). I also bought some 1/2″ diameter, 1/10″ thick rare earth magnets. Today my wife sewed things up (and very nicely too) and I think it works out well.
The idea was to be able to have the shiny side in for winter camping – keep the heat in, and the shiny side out for summer camping – keep the solar gain down. I had thought about using snaps to fix the blanket in place but magnets seemed more versatile. I think it turned out well.
I’ll post a bit more on the construction later.
