Embroidery Tinting with Crayons, Colored Pencils and Paint. When filling an area of embroidery, we usually think of fill stitches like the basic satin stitch or long and short stitch. Another way to add lots of color to your stitching, without lots of labor, is to use a technique known as embroidery tinting.
A Variety of Pressure Creates Emphasis. If there are some areas you want to accent, you can press a little harder on the crayon and end up with a darker, more intense color. This is another good reason to color lightly for full coverage. For example, in this picture of the heart below, I pressed harder when tracing the lines within the heart and in the vein and artery openings. I did the same thing when coloring the muscles and the brain.
