Search online for a cobweb image you like. If you want to trace the image, print it and shrink/enlarge to the size you want. Or you can just draw it freehand with the glue. It’s ok if it’s not perfect, I don’t think glue spiders worry about that sort of thing. Plug in your glue gun and set out a piece of parchment paper at your
kitchen counter workstation. Wax paper, foil and plastic wrap will NOT work instead of parchment paper – trust me. If you’re tracing the image, arrange it beneath the paper. Once your glue is ready to use, start drawing your web. I started from the corner/center and drew lines out, then filled in with the swoopy lines going across.
Peel the web off the parchment paper once it’s cool and press it onto your windows or mirrors, with the bumpy side to the glass. I suppose the spiders are optional, but if you want to add them for that extra eek factor, follow the same instructions as above. I used a purple glue stick for the spiders and started by swirling a dot of glue for the body, then swooping legs out from it. Glue spiders aren’t worried about their figures, either, so they can be a little messy. Nestle them right into the web once they’re cool. Or, just add a little extra glue to the web and stick a plastic spider right into it, like I did on this vase. It's important to note that you should not hot glue directly onto the glass.
And that’s it! A super simple, inexpensive way to add a little more to your Halloween décor. You’re friends are going to be so jealous that you have spiders and they don’t.
