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.)
