    Sewing Directions:

    Half Square Triangle Units:

    Step 1:

    Using the two Light/Ivory 3″ squares and the two Assorted Prints 3″ squares, sew together four Half Square Triangle (HST) units as shown in the picture below. Trim/square up the units to 2.5″ square. You can find my tutorial for making a basic Half Square Triangle at https://quiltembroiderypdf.com/how-to-sew-a-basic-half-square-triangle-block

    Rectangle Unit:

    Step 4:

    The Rectangle unit is constructed just like a Flying Geese block except that a longer rectangle is used. First you draw a diagonal line from corner to corner on the back of the remaining Assorted Prints 2.5″ squares and sew them to each end of a Light/Ivory 2.5″ x 6.5″ rectangle (top image). Then match up the corners, press (2nd image), and trim the seam allowance (3rd image) to create the Rectangle unit (bottom image).

    Putting It All Together:

    Lay out the Half Square Triangle units, the Nine Patch unit, and the Rectangle units as shown in the picture below.

    The same as the one above but with cornerstones and sashing added. What a difference!

    Here’s an example done with just a light and a dark.

    So with two darks and a light, this is what it might look like:

    Put that same quilt on point. It always amazes me how different an on point layout looks!
