These directions came from Crafty Visions 1999 on line news letter
Crafty Kids.....
Millennium or Y2K Bugs

Materials:

Pom pom
Chenille stem
Clear plastic from soda bottles
Craft glue
Wiggle eyes
Pin back or hanger cord
Glitter
Permanent marker
Option: trims, embellishments and accessories
Instructions:
If you make a pretty bug, butterfly or dragon fly it is a Millennium bug but if you want to make an ugly, scary, funny one then you have made a Y2K Bug.

Use your imagination to build your own bug. The chenille stem can be used as legs or antennae. Pom poms in different sizes can be used for the head or the body. The plastic in drink bottles can be used to make wings.

Draw different shapes on your cut out wings with the glue and sprinkle with colored glitter and allow them to dry. Glue the head to the bodies, the antennae to the head and the legs on the bodies. We have a few samples shown. Use them as a guide but have fun and invent your own Millennium or Y2K bug.

Option: Using trims, embellishments and accessories you can dress and decorate your bugs.
