Using a silver or metallic colored pencil on dark needlepoint canvas is a great trick to see the grid intersections better. How to Use It Apply Gently - lightly rub the pencil over the dark canvas intersections where you need more visibility. Stitch Over It - stitch as you normally would; the silver is designed to be covered by your stitches and won't show through. Why It Works Creates Contrast. It temporarily lightens the dark value of the canvas, making the holes stand out. Harder Lead. Unlike soft graphite pencils, the harder lead doesn't smudge excessively and covers the canvas effectively without being too messy. Disappears. It's a temporary solution that gets covered as you stitch, saving your eyes from strain. *For shipping orders pencil sharpener color is sent at random.
