I am a stickler for blackout actually being blackout. I’ve tried SO many different solutions for blacking out my kids windows, from blackout curtains, to cardboard on the windows, to portable ones, to even hanging my clothes over the curtain rods to block out the bits of light coming in. But FINALLY I have found a solution that not only works but looks nice (and as though I have my sanity intact!) They’re also easy to install. I have just ordered a second pair for another room in my house. I’m so impressed. The cherry on top was they arrived 2 days before the delivery window they gave me. Highly recommend!
