Graphite is a 3B pencil. It has a workable soft lead that can bring a beloved pet to life. I also use other graphite that is softer, depending upon the desired need. All pencil portraits are sprayed well to prevent any smearing. I also used a kneaded eraser to add lines and detail.
With either color pencil, or graphite portraits, make sure a mat is placed between the glass and the frame. This mat will enhance your portrait and portrait it from any condensation.
