Constructing the window
Now that I have a rough background, I work on the stained glass. I consult some reference sources and then create a new layer. I choose a Hard paint brush and draw a rectangular structure, topped by a pointed arch. I divide this structure into several other rectangles and add decorations to the top part. Here is my stained glass frame, ready for colouring.
Designing stylised figures
Saints and clerics were often depicted in stained glass windows. With the same Hard brush, but at a smaller size, I paint a figure for every vertical sector, based on my reference. I draw the important features of saints: tunics with accentuated folds, halos, and hands posed dramatically. The stained glass window is now ready to be coloured.
