Here are some photos of the workshops in action. It's great to be able to build on tables but a gymnasium floor is a fine substitute. The kite sails are usually precut and the kites are assembled with tape so there's no sharp tools or messy glue involved.
Look through the photos below... these people are creating art that flies. Once you've learned to make a kite you can build more. If you don't have time, the kites can be decorated at home using magic markers.
