So I’ve bought a Subaru forester with a bed in the back. Next I need to use something to cover all the windows at night for privacy. I’m thinking how about I cut out the window outlines into a material and then use maybe suction cups to stick the material onto each window? The question is which material should I use and would cutting mini holes in the material to attach the suction cups work? (Maybe aluminium insulation?) If someone has a better idea all together I’m all ears! Never done diy before so this is all new to me. Thanks!
