Color Outside the Lines Sometimes. In some circumstances, like this one, you can color outside the lines because you'll cut the piece out afterwards. This allows you to use large consistent strokes, as you can see in the red kidney above and on the right. This is an especially helpful tip for younger students who are coloring the organs in this My Body project. (Just be sure not to use this tactic on the upper half of the heart in the My Body book because we won't trim around all those veins and arteries.)
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.
