ART OF STAINED GLASS
The sketch is traced with a marker, and cleaned up. Some pieces are going to be too small, but judged to be essential, so the pattern will be enlarged.
Scan, enlarge and print

Four sheets of clean, white, plain paper are assembled with adhesive tape, abutting each other, without overlap. The printout is placed underneath it, and the pattern is re-traced in its final dimensions using a lightbox.
