Some colors are more transparent than others. Some colors are very opaque. Test your colors on a separate piece of paper to see how they work together. Too many layers of crayon can make the colors resist each other. This can make it harder to add more color. Use as few colors as possible to get your end result. Scratch out small lines and details (such as hair, the veins in leaves and flowers, etc.) with a craft knife. Crayon is excellent for scratching due to the wax. Do not get frustrated! You will need practice to get the look you want. It's worth it!
Colored Pencil Tinting . Embroider the design as desired. Tinting with colored pencil is similar to working with crayons. The result is much softer and it works well for blending color. The color is less colorfast than other tinting methods, so reserve this technique for embroidered items that won't be washed.
