Making the cathedral windows

Take your one 8” square, fold in half RST, stitch along the two short edges, using ¼” seam allowance.

Pull this open, bring seams together and sew along the two raw edges, leave a 1.5” gap in the centre for turning.

Press and turn your square the right way out, push the corners out using a chopstick. Hand sew up the gap and press again.

Repeat this process for the remaining 14 squares

Press the points to the centre of the square

Pin the squares together, so you have 3 rows, of 5 squares, then sew a line of stitches using Gutermann thread, colour 1288, along the crease, where the two squares meet.

This will allow the corners to be folded back into the original position.

Join the rows in the same way.

At this point, you are finished with your sewing machine, this now becomes a fabulous project for taking anywhere with you.

Take your 2 ¼” white squares and pin in place, see photo below for placement.

To hold these white squares in place, you first need to sew each point of the folded triangles down.

With a needle and thread, stitch a bar tack at each corner, roll back the turquoise fabric over the top of the white fabric and stitch tiny stitches to hold in place.

Once all your white squares are in place, its time to create the cushion cover…

Take the 4 strips of French navy fabric and create a frame.

Begin by pressing a ¼” seam along one long edge of the two longest strips.

Sew together the strips at the corners, see photo below.

Pin your cathedral windows in place, and top stitch in place, around the edge.

With RST sew the two turquoise pieces to either end of the French navy piece. Double fold a ¼” seam, on one edge of the turquoise fabric, press and stitch two lines of stitches.

With RST sew the two bigger pieces of French navy together and repeat the double fold seam on the end of the smaller piece of fabric.

With RST sew down each edge of the French navy piece, creating a pocket (like a pillowcase)

Take the top and back of the cushion and with RST, sew down one long side, across the bottom and back up the other side. Press and turn right way out.

Insert your cushion and fold over the pocket to keep it enclosed
