Blue chiffon, 1.5m x 1.5m
Front and back: Cut two 50cm x 114cm rectanglesNeck band: Cut bias strip, 20cm x 70cmArmhole bands: Cut two bias strips, 3.5cm wide, and long enough to fit around the armholes, 58cm1.5cm seam allowances are used throughout, except for the neckline where a 1cm seam allowance is used.
Fold the rectangles in half lengthwise. Use the guide at sewmag.co.uk to cut the necklines and armholes. Neaten the edges of the shoulders and side edges on the front and back tunic by using zigzag stitch. Match the shoulder seams of the front and back pieces together, then pin and stitch right sides together. Press the seams open.
Stitch the two ends of the neckband right sides together to make a circle, then turn out and fold in half lengthwise. Match and pin the neckband to the front and back neckline, raw edges together. Stitch in place with a 1cm seam allowance and neaten the seam edges using zigzag stitch. Understitch the neckline on the right side of the tunic, close to the seam line, securing the seam allowance down inside the tunic.
Fold and press in 1cm on either side of the two armhole band strips or use a bias binding maker. Open one side of the bias strip and position it around one of the armholes, from one side of the underarm to the other. Pin and sew along the fold line pressed into the bias strip. Fold the strip over onto the wrong side of the armhole and position the remaining folded edge over the stitching line. Pin and edgestitch in place, sandwiching the raw edge of the armhole inside the bias binding.
Trim any excess binding at the edges of the underarm, then repeat for the remaining armhole. Align the underarm and side seams together. The stitching line for the side seams should be approximately 25cm long, or to your waistline, and the remainder of the side edges will become the splits. Fold and press 1cm across the base of the front and back of the tunic, then another 4cm.
Turn the pressed hem to the right side, then stitch the side edges and turn back out. Turn the neatened edges of the side splits twice. Pin and edgestitch in place to make roll hems that finish just inside the base of the side seam and on the side edges of the hem. Pin along the hem and edgestitch in place.
