Peel and stick wallpaper is a game-changer for easy home decor! Start by prepping your wall: ensure it's clean and smooth. Use a level to align your first panel, and peel back a few inches to position it correctly. Smooth it down with a squeegee and gradually peel more as you go. For corners, cut panels accurately and utilize a hairdryer to ease adjustments. Enjoy your new look effortlessly!
