Learn to make a 3D Flying Geese quilt block out of a rectangle and two squares.
No lines to mark.
Perfect points every time.
And just one seam!
This method is for traditionally sized Flying Geese units that finish twice as wide as they are tall.
For our 3D flying geese quilt block that finishes 2-1/2" high by 5" wide, cut:
Fold the rectangle in half, wrong sides together. A finger press is good enough. You don't need to create a crease mark only to remove it later.
I used a print so that you can clearly see that the pretty side is on the outside.
Layer the pieces together in the orientation that they'll be fed through the sewing machine.
Lay out a sky square, right side up.
Lay the folded rectangle on top, align the short edges of the rectangle with the bottom of the square. (Note this folded rectangle is 1/4" shorter than the sky square.)
With right sides together, layer the final sky square on top, matching all edges with the first square.
The fold must be a quarter inch in from the edge.
Stitch a scant quarter inch along the side that intersects the fold of the geese fabric.
To avoid pressing a hard crease into the geese fabric, don't press the whole unit. Just press along the line of stitching to set the sea.
Open the top square and finger press the seam allowance to one side.
Open the 'goose' rectangle and match the long edge to the long bottom edge of the sewn squares. Finger press the 'goose' into place. When you are satisfied, then press the whole unit with your iron.
The bottom edge of the goose should be aligned with the lower edge of the sky squares. The geese side points should bisect the sky square corners.
Use your ruler to confirm that the unit is the correct size and that the point of the 'goose' is 1/4" away from the edge.
You may want to machine baste along the bottom of this unit to hold the 'goose' neatly in place until you use the unit.
Your 3D flying geese quilt block is finished.
As you saw above, the calculation is pretty straight forward for this unit—no wonky math—but it's still nice to have the calculations made for you and I've done just that.
