These shades are great! A little tricky to cut if all you have is regular scissors (box cutter would def have been easier/straighter), but luckily the remaining factory-cut edge can be used as outside one once fanned out! Also to install - recommend uncovering part of the adhesive and sticking to the central piece first, then uncover the rest of the adhesive strip and stick to the window frame or top of your regular blinds. You can fan out better once in place. The adhesive is strong enough, so glad (clean well before sticking). The shades are helping a lot with shielding the rooms from cold, but still let in a little light. I’m looking forward to seeing how it goes in the summer months. Definitely worth it!
