Get even! Producing a nice even color with your coloring pencil is all down to pressure. Push harder on your page for darker coloring, applying little pressure will producer a much lighter color. It is tempting to put lots of pressure on the pencil to produce the darkest color _ don't do it! Too much pressure will likely cause you to break your pencil leads, produce a scratchy finish to your coloring and give you less control. Instead, try applying your pencil with a little less pressure and use small circular motions with the pencil to get an even finish.
Crayon Tinting. Using crayons for tinting embroidery is the most common technique. It's easy to learn and most people have at least a few crayons around. Crayons produce a bold color, but you can also work more gently with them, resulting in a lighter tint. Just like coloring on paper with crayons, varying the amount of pressure and layering your coloring creates some very cool shading. That shading gives your embroidery texture and dimension, and it's fun to use with modern or vintage designs.
