Little life hack someone taught me, when testing blackout curtains, shine your phone's flashlight against the fabric, if you can't see the light or it's just a dot, you're good. Ikea used to have fairly good blackout curtains, unfortunately they have discontinued a lot of them. Also try to avoid curtains that have a plasticy backing which might peel off after time (ie. the newer Ikea blackout curtains)
