Download the pattern from sewmag.co.uk, then print out and follow the cutting guide. Apply fusible interfacing to the wrong side of the back neck facing, front facings, cuffs, front bands and back band. With right sides together, pin and stitch the fronts to the back at the shoulder seam. Neaten the edges, then press the seams.

The front facing is wider at the shoulder than the back neck facing. With right sides together, pin and sew the front and back facings at the shoulder seam. Press the seam open. Neaten all outside edges and the wider part of the front facing.

Pin the facings to the front edge and back neck, right sides together, matching the shoulder seams. Sew the facing to the edge of the top all the way round. Clip the curves at the back neck and trim away any excess. Understitch the seam all around the facings.

Turn the facing to the wrong side of the top and press. Secure the extra part of the front facing in position at the shoulder seam with a few catch stitches along the seam allowance. Neaten the raw edge at the bottom of the front facing.

On the right side, topstitch the back neck facing around the neck edge from one shoulder seam to the other. With right sides together, pin each sleeve in position, matching the notches and sew. Trim the seam and neaten the edges together with an overlocker or zig zag stitch.

Neaten the three sides of the placket by turning under a narrow hem. Position the placket over the marked V position on the sleeve, right sides together. Sew along the V-shaped line pivoting at the point, then back up the other side. Cut down the centre of the V as far into the point as you can, and trim excess fabric from the seam allowance.

Turn the placket to the wrong side of the sleeve and press the edge. Fold under the finished edges of the placket and topstitch in place. With right sides together, pin the sleeve seams and side seams, matching notches and underarm seams, and sew. Neaten the seam allowance and press.

Stitch a gathering thread at the bottom of the sleeve between marked points. Fold the cuff in half, right sides together, and sew the ends. Trim the seam and corner, then turn the cuff to the right side. Press the ends of the cuff and the folded edge. Press under a 1.5cm seam allowance on one edge of each cuff. Pin the unpressed edge of the folded cuff to the sleeve edge, matching notches and pulling the gathers to fit.

At the buttonhole side, the cuff meets the edge of the placket, and at the button side, it extends by 2.5cm. Stitch in place. Press the seam allowance towards the cuff. Working from the wrong side of the sleeve, fold the pressed edge of the cuff over to meet the seam and hand-sew in place or machine-stitch close to the edge.

Make the buttonhole where marked and sew on a corresponding button on each cuff. Stitch a gathering thread around the bottom edge of the fronts and the back sections. Do not sew across the front facing, instead fold it away from the edge while you add the gathering thread.
