Materials

Instructions

  • On a flat surface, roll each clay color into strips about 5 inches long. For your primary color (or white), make a roll slightly smaller than the diameter of a quarter. Make smaller rolls of secondary/highlight colors. The amount of each color you use will change the look and feel of the final project.

  • Twist the rolls together in a chain. Roll and gently stretch until smooth and well incorporated. Fold in half and twist several times. Roll and stretch the twisted clay. Use your hands to knead the the colors together, to blend colors and create finer striations.

  • Roll your chain into a ball and flatten with your palm on a smooth surface. Using a rolling pin or acrylic roller, flatten out the ball to at least 3.5 inches in diameter. Check for any apparent bubbles trapped in the clay. You can remove with a pin if necessary. Pick up to make sure it doesn’t stick to the board.
