The vinyl is really transparent and I had to take more than one photo to make it show so you could see it. When you're in the dining room, you sort of look through the webs and hardly notice them. The vinyl sticks to the windows by itself, just like a screen protector on an iPad, without any adhesive. Our hope is the birds will see the webs and choose a different route. I mean, who doesn't hate running into a spider web, right?
