Royal Letter Seals


Send off top-secret, highly classified letters with a royal flair! Seal them like kings used to do, with bright red seals.


1. Long ago, people’s letters were hand-carried to recipients. To keep their words private, they folded the letter and put a spot of melted red wax over the edges. To prove they were the sender (and to reveal if the letter had been opened before it was delivered), they pressed their insignia or seal into the wax. Find examples of this practice in myths and history, such as in royal and military correspondence.

2. To make your own seal, roll a tiny ball of Crayola® Air-Dry Clay. Press it flat with your hands. Then press objects, such as a marker cap, coin, or leaf into the clay to make a pattern. Air-dry your seal at least 24 hours.

3. Cover your art area with newspaper. Paint your seal red with Crayola Tempera Paint and Brushes. Air-dry the paint.

4. Write an important letter with Crayola Erasable Colored Pencils. You can easily make corrections! Address the envelope and insert the folded letter.

5. Use Crayola School Glue to attach your red seal to the flap for maximum security. Air-dry the glue before you give your letter to a friend to deliver it.

Safety Guidelines

Adult supervision is required for any arts & crafts project. Observe children closely and intervene as necessary to prevent potential safety problems and ensure appropriate use of arts and crafts materials. Some craft items, particularly beads and buttons, are potential choking hazards for young children. Avoid use of such small parts with children younger than 3 years. Craft items such as scissors, push pins and chenille sticks may have sharp points or edges. Avoid use of materials with sharp points by children younger than 4 years. Read all manufacturers' safety warnings before using arts and craft supplies.

Crayola Modeling Materials including Crayola Model Magic®, and Model Magic Fusion™, Crayola Air-Dry Clay, and Crayola Dough—

  • Keep away from open flames. Do not use to make candleholders, hot plates, trivets, or other similar objects that will be used or placed near fire and other heat sources.
  • Do not put in an oven, microwave, or kiln.
  • Do not make into vessels/containers that will hold unpackaged food.
  • The use of modeling material to make items that look like food is discouraged for children younger than age 5 to avoid their confusion with real food.
  • Unless sealed with a water-resistant glaze, do not make projects exposed to or immersed in water, such as boats or outdoor bird feeders. They would disintegrate when exposed to moisture.
  • Crayola Dough—contains gluten (wheat flour) as an ingredient.
  • Crayola Air-Dry Clay, Crayola Model Magic and Model Magic Fusion are gluten-free. However, they are produced on the same machinery as Crayola Dough which does contain gluten. Although the machines are cleaned prior to the start of each production run, there is a slight possibility that trace amounts of gluten from Crayola Dough may be present in the other modeling compound products. For information regarding specific ingredients or allergic concerns, please call our Consumer Affairs department at 1-800-272-9652 weekdays between 9 AM and 4 PM Eastern Standard Time.

Crayola Washable Paints—Not for use as body/face paint.


  • Write letters in a language that children are studying rather than their first language.
  • Recreate historical correspondence using sealed messages between military or government leaders.
  • Write fiction about the adventures of ancient letter carriers.
  • Research current postal systems in your own and other countries. How are they funded? Organized? How is mail delivered? How long does it take for letters to get to different destinations?
  • Compare the use of wax seals to Internet security. How are they similar? Different?
  • Assessment: Ask students to describe how they impressed a pattern on their seal. Review letters and envelopes for spelling, grammar, or other conventions.
