My first thought is to use permanent markers and create mini stained glass ornaments. Haven't tried this, but it's a thought.

I have saved about 200 Dannon yougurt lids. They are clear circles with blue outlines and are plastic.
I had in the back of my mind that I would do ornaments this year with them but haven't formalized a plan.
Any super creative scavenger-type art teachers out there have a suggestion?
