1. Cut black paper to 2.5″ x 3.5″ standard ATC size. Draw about 8 straight lines radiating out from a center point on a card. I used a white Pen Touch permanent paint marker.
2. Draw concentric rings around the center point. Try to make them dip a bit from point to point for a realistic look. My top left card was drawn with just straight lines, and I decided that I liked the curved lines much better. Repeat for nine cards. Add spiders if you wish.
3. Place all the cards in a Trading Card sleeve and collect in a notebook.
