The secret to this technique is having a fine liner glue bottle like the ones they use in quilling.

1. Choose image and identify areas that might benefit from some sprakle.
2. Using the fine liner bottle and glue, add glue to areas where glitter will be.
3. Highlight one color at a time. Add glue to all the places that will be green, pour green glitter over the image. Pour off extra glitter.
4, Repeat for each color.
5. Let dry.
