Step 3: Measure Glass, Design and Print Tracing Paper Sheets
In your favorite drawing software (e.g. OpenOffice Draw), create a trapeze of measured sizes to mark the borders, and import a picture of your choice. Size it to fit into the trapeze.
Personally, since I only had tracing paper on hand, and after some trials, I choose some black/white Japaneses patterns:
- tracing paper prints best with a laser printer (with inkjet, it will form a roll when still wet).
- The contrast is maximum, with lots of black areas (which will give a more intimate atmosphere);
- tracing paper is a great diffuser on white areas.
