So not the most complex of crafts, but my kid was pretty stoked to make and wear some pipe cleaner glasses. We even made a matching pair for his favorite stuffed piggie.
A good diagram and instructions are here
Take 1 pipe cleaner and wrap one end around in a circle.
Then wrap the other end around in a circle leaving a space in the middle between the 2 circles.
Take another pipe cleaner and cut it in half.
Wrap one piece around each of the circles. And there you have it – glasses!
