How to design a stained glass object

Task 1): You are the expert. You know which steps have to be taken to sketch a design for a stained glass object. As you know, we have a lot of journeyman's pieces of former students at our college. The headmaster has decided to print a catalogue of these objects with explanations to hand it over to foreign visitors on the regular day of open house in November. Please write an appropriate text and describe how to sketch a specific design, which pencils and materials to use, and which drawing techniques to apply. Choose one of the objects and put your text into the Glass Classroom.

Task 2): Visit this online web tutorial in doing a design for stained glass patterns. Describe the way of transferring a photograph into a design for a stained glass. Put your text into the Glass Classroom.
