Custom-designed ruler has a non-slip surface on the bottom side for easier cutting and better fabric stability. Clear ruler with black lines for proper visibility and alignment. Diamond / Rhombus measures 10.5″ inches from tip to tip. Largest triangle measures 5 3/4″ inches from bottom side to tip.

This ruler features two 45 degree triangles to form a perfect diamond. Use a triangle side to measure and cut triangles from a charm pack (makes an adorable bunting)! Or, use the entire ruler to cut a perfectly-shaped diamond as the center of each point of this Christmas Star tree skirt. (Pattern coming soon.)
