1. Cut black paper to 2.5" x 3.5" standard ATC size. Draw about 8 straight lines radiating out from a center point. I used a white Pen Touch permanent paint marker.
2. Draw concentric rings around the center point. Try to make them dip a bit 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.
3. Place all the cards in a Trading Card sleeve and collect in a notebook.
