Cover your work surface with newspaper to protect it from glue when making this spider web decoration. Blow up a 9-inch balloon and tie off in a knot. The size of the balloon will determine the size of your web. Cut twenty 6-foot pieces of black yarn. Finally, mix together equal portions of glue and water. You now are all set to become an honorary spider and make this Halloween spider web craft.
Dip a piece of yarn into the glue mixture until it soaks thoroughly, making sure not to tangle the yarn. Pull out and gently squeeze off excess glue by running yarn between index finger and thumb. Then wrap the yarn around the balloon in an irregular pattern, criss-crossing the balloon. Continue with the remaining yarn pieces, tucking in the end of each piece beneath the yarn layers. To finish, tie a length of string around the balloon knot. Hang up the balloon and let dry completely. (We recommend putting newspaper under the balloon to catch any drips.)
To finish this balloon craft, make sure the glue is completely dry and pop the balloon. Use tweezers to pull out the deflated balloon and any glue residue between yarn pieces. Hot-glue plastic spiders to the web, and tie a piece of string to the top to use as a hanger. You can place this spider web decoration in any corner of the room or over a treats table as a Halloween party decoration. Create multiple webs for a spooky hanging display.
