1 cm Triangular Graph Paper — Letter
With 1 cm sides, the grid opens up for quicker, larger work. The roomy cells give children and beginners space to draw shapes and color individual triangles, and they make brainstorming tessellation or origami-fold layouts faster to sketch. One centimetre is also easy to count in your head for rough scaling, so it works well when you want the structure of a triangular grid without fussing over fine detail.
