Don’t worry about them leaving glue behind — they stick by themselves using static and come off just as easily. I put these on my own windows last year and it was super simple! They look beautiful, too.
Tip: It’s a good idea to wipe down your windows before you put these on!
Promising review: “Really enjoyed the colors of fall with this set — you definitely get your money’s worth, as there are so many to choose from. You can put fall up on every window in the house! They went on great, but more importantly, they came off super easy unlike the other brand I bought for Christmas. This brand’s stickers were heavier plastic, easy to apply, and came off just as easy. Just keep the paper they came on, peel them off your window(s), and put them back on the sheet (basically in the same spot, as you can see the shape of each leaf). The colors and details were vivid and life-like. Very lovely.” —Jo Anne Maarten
