 Instructions for Cutting Quarter-Square Triangles

Quarter square triangles are cut so the hypotenuse (long side) of the triangles is on the fabric straight of grain. Select black line on ruler that corresponds to the desired finished size of the long side of triangle. Solid lines are for even inches and dashed lines are for 1/2 inch increments. Follow the line across to the right edge of the ruler and cut a fabric strip the width indicated. For example, to cut a 4 inch finished quarter square triangle, cut a 2-1/2 inch wide strip. Cut triangles as shown, first placing the cutting guideline along the bottom cut edge of strip and then along the top edge of strip.

Instructions for Cutting
Half-Square Triangles

Half square triangles are cut so the legs (short sides) of the triangle are on the fabric straight of grain. Select yellow line on ruler that corresponds to the desired finished size of the legs (short sides) of triangle. Follow across the line to the left edge of the ruler to find the width to cut fabric strip. Cut a strip this width. For example, to cut a 4 inch finished half square triangle, cut a 4 1/2 inch wide strip. Cut triangles as shown, first placing the cutting guideline along the bottom cut edge of strip and then along the top edge of strip. The yellow shaded area of the ruler will extend beyond the edge of the strip.
