Redi Shade No Tools Original Blackout Pleated Paper Shade Black, 36 in x 72 in

Mine have been up for years with tension rods. There's also these blackout blind things. They're just thick paper and sticky at the top but I've had a set up for a while that's held up really well. https://www.walmart.com/ip/902667015?sid=456bf8be-d733-42a8-9d53-084f14450433
