Cut several small slits evenly spaced around the edge of the paper plate.
Paint the paper plate with the black paint and allow to dry completely.
When the paint is dried, wrap the white yarn around and around the paper plate to form a spider's web. The yarn should be "woven" in between the slits and rest securely in the slits.
Leave one end of the yarn hanging down off of the web, so you will have enough yarn to attach the spider.
Tie a loop at the top of the web to allow you to hang the web from the ceiling.
To create the spider, cut two circles (both the same size) from black construction paper.
Paint one circle with white liquid glue and place four twist ties across the circle, so that they stick out on each side. These will be the spider's legs.
Paint the other circle with glue and "sandwich" the twist ties between the two circles.
Glue on wiggle eyes.
After the glue dries and the twist ties are secure, bend each tie to form spider's "knees".
Attach the spider to the yarn hanging from the web by putting the yarn in between the two circles. Glue to secure.
Allow glue to dry completely before hanging from the ceiling or door.
