Things you’ll need:
Pencil with an eraser
Stamp pad or markers
Things to do:
1. Sketch a equilateral triangle onto the end of the eraser. Trimming the end first if the eraser has been used to make sure you have a flat working surface.
2. With the craft knife, carefully cut straight down on the lines and then trim away the excess, leaving only a triangle.
3. Ink with the stamp pad or markers and then stamp, point to point, like a banner, across any paper surface.
