Five A4 sheets of finest quality calque paper, transparent with a smooth surface. Use it for tracing or for creating transparent layered artworks.
To trace: secure the sheet of calque to your image with a small piece of tape, then use a pencil to trace the image onto the calque. Next, remove the tape, turn the calque over and draw over the pencil lines that you see through it (place the calque on a piece of scrap paper and use a soft pencil). Now turn the calque back over again and secure it to your drawing paper with tape. Draw over the lines that you drew first of all, pressing enough to transfer the graphite on the back of the calque to your paper.
