What is the formula for cutting quarter square triangles? To cut quarter square triangles, you’ll generally start with a square and then cut it into four smaller triangles. The formula would be to take the size of the desired finished quarter square triangle, add your seam allowance, and then cut a square of that size. For example, if you want 4-inch finished quarter square triangles with a 1/4 inch seam allowance, you would cut a 4.5-inch square.

What is a quarter square triangle? A quarter square triangle (QST) is a type of quilting block made up of four equal-sized right triangles arranged in a square shape. These triangles meet at the center, creating a pinwheel or hourglass design when multiple QSTs are combined.

How do you make quarter square triangles for quilting? To make quarter square triangles, you can follow these steps:

  1. Start with a square of fabric.
  2. Draw two diagonal lines from corner to corner, creating an “X” on the square.
  3. Cut along the diagonal lines to create four equal-sized triangles.
  4. Sew the triangles together in pairs along the long sides.
  5. Press the seams open or to one side to reduce bulk.
  6. Sew the two pairs together to form a quarter square triangle block.

How do you make a 4-inch half square triangle? To make a 4-inch finished half square triangle (HST) with a 1/4 inch seam allowance, you would typically start with a 4.5-inch square of fabric. Follow these steps:

Why do quilters use fat quarters? Quilters use fat quarters because they are pre-cut pieces of fabric that provide versatility for various quilting projects. They are larger than standard quarter-yard cuts and allow quilters to work with a wider range of fabric designs and create more intricate patterns.

How do you keep points on a triangle when quilting? To keep points on a triangle when quilting, pay attention to precise seam allowances, pinning, and pressing. Carefully align the fabric edges at the point, pin to secure, and press seams away from the point to reduce bulk.
