how to use the sand paddle and tortillion in my SketchMate set?
i jus got a set of charcoal and graphite drawing pencils, they also came with the eraser,shapener,and somthing called a tortillion,and a sand paddle. what to do with these last two objects?
The tortillion is for blending instead of using your fingers and the sand paddle is for sharpening the tip of your pencils to save on wasting when you sharpen with the sharpener. You use the sharpener when the lead is no longer visible or worn too low to use
