The only thing I stick to the fur is some Velcro that we use to keep the curtains open. When I yank it from the fur, there is no lifting, it holds well. I am thinking of getting some Reflectix, cut it to the size just larger than the windows
and stick it to the fur over the windows
by means of the "hook" part of Velcro (Velcro is a trademark, generically it is hook-and-loop) to keep heat in for those cold "spring time" excursions. Is Reflextix tough enough for repeated handling? Or is there something better? Has it been tried or am I whistling in the cold wind?
