This year at work I wanted to do decorating that was friendly to my co-workers and my budget, easy to remove later, and going to make big impact. So, I went with washi tape spider webs. I used Martha Stewart Halloween prints, but you can use whatever you like. I also added some dimensional spiders that I purchased from Target, but I plan to make some of my own out of craft foam and card stock. It's a very basic process; pick a spot and make a sort of grid, add a spider. Enjoy!
It's very basic: pick a spot to put the web, find some washi tape or painters tape that you like, create "rays" at varying angles that meet at the same point, fill in the rays with segments, pop a spider on it. Boom! You have a faux spider web.
