Download the pattern, then print and follow the cutting guide. Apply fusible interfacing to the wrong side of the placket. Draw a line on the surface of the interfacing at the centre of the placket with a water soluble fabric pen. Neaten both sides and the bottom edge using an overlocker or zig zag stitch, or by turning under a narrow hem.
Place the placket at the neck edge of the centre back T-shirt, right sides together with the placket facing you, and pin. Stitch 5mm either side of the centre line and two or three stitches across the bottom, 1.5cm from the bottom edge of the placket. Cut down the centre of the stitching and snip into the corners. Turn the placket through to the wrong side of the back and press the edges. With wrong sides together, pin and stitch the front to the back at the shoulder seams. Neaten the seam edge using an overlocker or zig zag stitch and press towards the back.
Fold the neckband in half, lengthways and right sides facing, then press. Position the raw edges of the neckband around the neckline, working from the centre front to the back opening and pin in place. Open out the top edge of the placket and fold it back on itself.
Place the ends of the neckband over the top. Stitch around the neckline. Finish the edge by using an overlocker or by trimming the seam and using a zig zag stitch. Fold the placket back into the correct position. Finger press the seam downwards and topstitch close to the seam line around the neck on the right side. Slip-stitch the placket edge and neck band together at the centre back.
Make a button loop at the top of the placket on the left side using thread. Sew a button in the correct position on the righthand side of the placket. Make a button loop with doubled over thread stitched into the seam, then work tiny blanket stitches around it.
Position lace around the neck line. Take your time to arrange and pin it, clipping around the lace pattern and checking the design is symmetrical and angled around the curve. Hand stitch it into place. A purchased lace collar can be sewn onto a narrow piece of bias binding, then stitched into place.
Pin the sleeves in place, right sides together, matching the notches and circles. Stitch the sleeves and neaten the seam edge using an overlocker or zig zag stitch and press towards the sleeve. With right sides together, pin the side seams and the sleeve underarm seam, matching the notches and lining up the end of the sleeve seam.
Stitch from the wrist edge to the hem. Neaten the seam edge using an overlocker or zig zag stitch and press towards the back. Neaten the edges of the sleeve and the hem using an overlocker or zig zag stitch and turn up a 2.5cm hem on each. Press the hem fold and stitch in place.
