This 4-pointed design makes me think of a Celtic Cross. Celtic designs are often decorated with interwoven lines.

You can use any colors you want, of course.

For a subtle effect in this design, I used different shades of grey going from dark to light, ending with yellow glowing in the middle. I used the Staedtler pens shown below.

Instructions

1. Attach Ring 144/96 to your paper using the Spiro-Putty (or pins, if you’re using an old set and haven’t tried Poster Putty yet).
2. Using Wheel 72, line up Hole 1 with a line on the ring. Using a black pen, draw the design.
3. Line up Hole 3 with the same line on the ring. Again using black, draw the design.
4. Switch to dark grey for Holes 5, 7 and 9. Each time, align the line that goes from the hole to the edge with your positioning line on the ring.
5. Use light grey for Holes 11, 13 and 15.
6. Finally, use yellow for Holes 17 and 19.
