Our quick method for making Half-Square Triangle Quilt Units begins with two squares. A Fons & Porter Quarter Inch Seam Marker offers a neat way to mark accurate sewing lines for this method.

1. From each of 2 fabrics, cut 1 square 7/8" larger than the desired finished size of the Half-Square Triangle Unit. For example, to make a Half-Square Triangle Unit that will finish 7", cut 7 7/8" squares.

2. On the wrong side of the lighter square, place the Quarter Inch Seam Marker diagonally across the square, with the yellow center line positioned exactly at opposite corners. Mark stitching lines along both sides of the Quarter Inch Seam Marker (Photo A).

3. Place lighter square atop darker quilt square, right sides facing; stitch along both marked sewing lines.

4. Cut diagonally between rows of stitching to make 2 Half-Square Triangle Units (Photo B). Press seam allowances toward darker fabric.
