The coil cup challenged Charlie Deer very much, but he was able to persevere through it. He started by rolling small coils of clay to long rods. He then wrapped them around each other to get a creative design. He intentionally wanted his coil cup to look like worms swarming around on top of each other. Some of the designs include: making circular roatations, making roations from both ends of the coil to meet in the middle, and a horizontal swivel.
