Examples of interesting patterns are all around you, or refer to the crayon etching design sheet pictured above for some ideas. Try making a quilt block or a stained glass window design. Making a crayon etching can be very messy. Be sure to protect your work space with newspapers, especially for the inking process and the actual etching. If you must rest your hand on your picture as you work, place a scrap of paper underneath to keep your hand clean and to protect the artwork.
Mat board is nonrecyclable, so reusing mats helps save the environment and money.
Ask your picture framer to donate a good, used mat for your finished crayon etching.
