My son and I worked on a craft yesterday. He picked it out of "Usborne Knights and Castles Things to Make and Do" which can be found at Amazon.ca, at your local Library, or through an Usborne Books Consultant.
It was a cool craft, but I would not recommend it for anyone under 8. The "stained glass" is made of white glue and food colouring - so you can blend colours. It's pretty cool. Took about an hour and a half and then overnight drying. We did Knights as a theme at the library book club this week - so this was an extension of that.
