Stained Glass: Kids Medieval Project

When I visited Europe as a child, I remember being struck by the Gothic stained glass windows, and particularly the rose windows found in so many cathedrals- for their symmetry and massive scale.  So this year as we've been homeschooling through the Middle Ages, I found myself wanting to help my children interact a little with the beauty of Gothic stained glass somehow.  

I liked the way this project allowed my children to do their own work but create pieces that were unique and presentable.  I had envisioned helping them a great deal, but found that the the art mediums at both stages of the project were very forgiving.  My six-year-old and four-year-old made their windows almost entirely on their own. I think an older child could include finer detail and could maybe be more creative with the project.

Materials:

Glass rectangle from a small picture frame
