Great way to block out winter’s chill and keep out the summer heat! The Basic Warm Window shade is ideal for several situations! Use the Basic shade in RV’s, boats and you can even make one for over your drafty fireplace! Easy to make – just two hems and two seams – if you can sew a relatively straight line – you can make an energy efficient Basic Warm Window Shade! This shade uses hook and loop tape – no hardware necessary!
