Sewing instructions:

Fold the fabric right sides together and pin the pattern to the fabric.

Iron a 3 cm strip of vilene to the wrong sides of the fly and fly shield and 6 cm from the top edge.

With right sides together, pin the 2 front crotches together and machine stitch.

Press 1/2 cm of the right fly extension to the wrong side.

Fold the fly in half and pin and tack in place.

Machine stitch on the edge.

Press 1 cm of the left fly extension to the wrong side.

Pin the right fly extension on top of the left fly extension.

Mark the stitching line as illustrated. Machine stitch in place.

Overlock the crotch seam at this stage.

Tack the left fly extension to the garment. Machine stitch on the folded edge and up to the previous stitching line.

Make a mark for the buttonhole on the right side. Sew the buttonhole and mark the position of the button on the fly shield.


Sew the button in place. The front is now complete.

With right sides together, pin and stitch the centre back seams together.


Pin and stitch the inner leg seams together.


Fold the leg hem over 1/2 cm and press. Fold over 1 cm and press. Pin/tack in place and machine stitch the hem.

Pin and stitch 6 cm down on the centre front panel to hold the two fly extensions together.

Cut the required length of elastic. Overlap the two ends about 2 cm and use a zigzag stich to sew it together.

Devide the waist in 4 with pins. It also known as quarter pinning. Repeat the same for the elastic.

Place the elastic on the wrong side of the shorts, while matching the pins of the shorts and elastic.

Overlock the elastic to the waist, while stretching the elastic at the front and back simultaneously.

Fold the casing over and pin in place.

Machine stitch the edge of the casing while stretching the elastic at the front and back. Stitch the centre of the casing while stretching the elastic at the front and back.

Voila! The shorts is completed.
