Who this list is for
A 12-year-old who needs a small pencil and marker organizer can make this marbleized clay pencil cup. It uses air-dry clay over a cardboard tube and is not food-safe.
How to use this list
Cover the table with the disposable work mat and set out wax paper sheets. Roll and twist together the three air-dry clay colors on the silicone clay mat to create a marbleized look. Use the clay roller to flatten the clay, wrap it around the cardboard tube, and trim it with the plastic clay knife. Smooth seams with the clay smoothing tool, then let the cup dry. Sand carefully with fine-grit sandpaper and add water-based craft sealer using the foam paintbrush.
Common mistakes
Do not use the finished pencil cup for food or drinks. Avoid wrapping clay so tightly that the cardboard tube bends, and do not make the base too thin. Keep the marble pattern visible by mixing colors only a little. Wait until the clay is fully dry before sanding or sealing.
