Peaky & Spike Templates - Marti Michell
A multi size tool is fabulous because you have every size of Peaky and Spike triangles between 1" and 6" every half-inch. The 1/4" and 3/4" increments were omitted to make the tools easier to read. If you need one of those sizes, just place a 1/4" wide tape above or below the appropriate line for a temporary guide. Peaky and Spike are typically used so that one small triangle is added to each side of the large triangle to make a square.
