The large windows in the Museum Schnütgen are made up of many colourful pieces of glass, held together with lead. This was how stained glass windows were made in the Middle Ages. The details, such as eyes or feathers, were then painted on in black. If you like, you can even make such pictures at home. Start out with the interactive sheet, which will tell you how you can make extra-large images with all sorts of designs and exciting colour effects.
