Sewing instructions:

For the Square in a Square you need 1 ~ 4 1/2″ Square (White Large Watermelon Fabric)  and 4 ~ 2 1/2″ Squares (Green Stripe Fabric).  Draw a diagonal line on the back of all four 2 1/2″ Squares. Place small squares on opposite corners of the large square.  Stitch on the line. Trim 1/4″ away from the stitching. Press towards the corners.


Add the other two small squares to the last two corners.  Repeat the process.  Stitch on the line, trim 1/4″ away from stitching, and press to the corners.  Trim this unit to 4 1/2″ Square.  Be careful to leave a 1/4″ at each point of the center square.


Flying Geese unit.   You need 1 ~ 2 1/2″ x 4 1/2″  Rectangle (Green Stripe Fabric) and 2 ~ 2 1/2″ (Ant Fabric) Per unit.

Draw a diagonal line on the back of the 2 1/2″ squares. Place a square on the right corner of the rectangle. Stitch on the line, trim 1/4″ away from stitching, press to the corner.

Paying attention to the direction of the line, place the second square on the left corner of the rectangle. Stitch on the line, trim 1/4″ away from the stitching, and press to the corner.  If needed trim to 2 1/2″ x 4 1/2″  making sure there is 1/4″ above the point of the goose.  Make two.



Half Square Triangles (HST) Unit.   For the small HST you need the 3″ Squares, The Green Stripe Fabric and the Black Small Watermelon Fabric.  Draw a diagonal line (Do you see a theme??) on the back of the Green fabric.  This time you will stitch 1/4″ away from the line on each side.  Cut apart on the line. Press to the Watermelon fabric.  Trim to 2 1/2″ Square. Each 2″ set will give you 2 HST.  Make a total of 4 sets (8 HST)

Sew two of these HST together.  Pay attention to the layout of the block.  This unit will measure 2 1/2″ x 4 1/2″.  Make 4 units.


Large HST with Snowballed Corner Unit.  Follow the same steps as the small HST.  Use the 5″ Squares (Black Watermelon Fabric and Green Stripe Fabric) and the 2 1/2″ squares (Ant Fabric). After you press to the Green fabric, trim to 4 1/2″ square.

Place the 2 1/2″ Square on the corner of the watermelon fabric. Stitch on the line, Press to the corner.  Trim to 4 1/2″ Square.  Make 4 units.

Lay all your units out to see how the block will look.  Sew the Flying Geese units to the Small HST units, press to the HST unit.  Sew the other two small HST units to the 2 1/2″ x 4 1/2″ rectangles. Press to the rectangles. Make two of each unit.  Measuring 4 1/2″ square.  Next sew rows together, press the top and bottom row in and the middle row out.  Sew rows together Press.  The block should measure 12 1/2″ Square.
