## Cutting Half- and Quarter-Square Triangles

## Cutting Half-Square Triangles (right-handed) [1]

1. Square up the fabric.

2. Cut the fabric in strips as wide as the desired finished width of the triangle-squares, plus 7/8” for seam allowances. For example, for a 3” finished half-square triangle, cut a 3-7/8”-wide fabric strip.

3. Square up one end of each strip.

## Cutting Half-Square Triangles (right-handed) [5]

4. Using a ruler, cut the strip into lengths equal to the strip’s width. In this example, the strip would be cut into 3-7/8”-long pieces.

5. Position the ruler diagonally across a square and cut the square in half to make two equal-size right triangles.

## Cutting Half-Square Triangles (left-handed) [9]

1. Square up the fabric.

2. Cut the fabric in strips as wide as the desired finished width of the triangle-squares, plus 7/8” for seam allowances. For example, for a 3” finished half-square triangle, cut a 3-7/8”-wide fabric strip.

5. Position the ruler diagonally across the square and cut the square in half to make two equal-size right triangles.

## Cutting Quarter-Square Triangles (right-handed) [17]

1. Square up the fabric.

2. Cut the fabric in strips as wide as the desired width of the quarter-square triangle, plus 1-1/4” for seam allowances. For example, for a 3” finished quarter-square triangle, cut a 4-1/4”-wide fabric strip.

4. Using a ruler, cut the strip into lengths equal to the strip’s width. In this example, the strip would be cut into 4-1/4”-long pieces.

## Cutting Quarter-Square Triangles (right-handed) [23]

5. Position the ruler diagonally across square and cut the square in half to make two equal-size right triangles. Do not move or pick up the triangles.

## Cutting Quarter-Square Triangles (right-handed) [25]

6. Position the ruler diagonally across the cut square in the opposite direction and cut the square in half again to make a total of four equal-size triangles.

## Cutting Quarter-Square Triangles (left-handed) [27]

1. Square up the fabric.

2. Cut the fabric in strips as wide as the desired width of the quarter-square triangle, plus 1-1/4” for seam allowances. For example, for a 3” finished quarter-square triangle, cut a 4-1/4”-wide fabric strip.
