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.
Always Color in a Consistent Direction. This is my first tip. It will make a bigger impact on the end result than anything else and any age can use it! The changes in direction, shown on the red kidney below, on the left side, are what make it look sloppy, even though I carefully stayed in the lines. Coloring in a consistent direction, as seen on the other kidney, is easier on the eyes and ends up looking very tidy!
