Cutting Triangles

HALF-SQUARE TRIANGLES
The straight grain of the fabric is located on the short sides of the triangle. Use half square triangles for the corners of the quilt.

QUARTER- SQUARE TRIANGLES
The straight grain of the fabric is located on the long side of the triangle. Use quarter square triangles for the sides of the quilt.

CUTTING LARGE TRIANGLES
Square the edge of the fabric (refer to Rotary Cutting lesson) Using two rulers for the extra wide strips, cut the fabric into strips.

Using the same method, sub cut strips into squares.

The grid lines on a cutting mat may be used as guidelines when cutting quarter square triangles.
