Perspective and proportion just got easier! Alvin Gridded Sketch Boards are made of smooth, white-painted hardboard, printed with a 1-inch grid that can be seen through many sketch papers. Helpful for perspective drawing and proportioning, they are also handy and economical for general sketching. Each has a spring clip and large rubber band to secure a sketchpad or single sheet, and a hand hole for carrying.
Board size: 15-1/2" x 16-1/2"
