Cut and mark fabric squares for your half square triangle units.

Begin Making the Quick Pieced Units

  1. Refer to your quilt pattern for the square size and number of squares required. If you are drafting your own pattern, cut squares that are 7/8" larger than the finished size of the units unless you prefer to create oversize HST units and then cut back for improved accuracy, see page 5.

    When calculating, remember that each pair of squares produces two HST units.

  2. Use a pencil or permanent marker to draw a diagonal line from one corner to the opposite corner on the reverse side of the lightest square.

  3. If you do not have a quarter-inch presser foot, draw two more lines, each one 1/4" from the original diagonal line -- extra lines are not illustrated.
