1 Download the template and use the Dimensions List to cut out the pattern pieces. Snip into the curved seam allowance around the neckline on the front pieces, then turn it over to the wrong side and secure the tabs with a glue pen. Fold over a narrow double hem down the edge of each front, folding it to the right side. Secure with a glue pen, then backstitch a line down both edges of the hem.

2 Spread glue onto the wrong side of each faux seam strip, then fold both raw edges into the centre. Add more glue and stick one strip to each front of the denim jacket, allowing the lower end to overlap the bottom edge. Backstitch a line down each strip, then trim off the excess.

3 Turn in the seam allowances around the edges of both pockets and secure them with a glue pen. Backstitch across the top of one pocket, then without cutting the thread, backstitch it in place onto the front of the denim jacket; the point of the pocket should overlap the faux seam by a tiny amount. Repeat to sew the other pocket onto the other jacket front.

4 Pin the two back jacket pieces right sides together. Backstitch around the neckline and along the bottom hem. Snip into the seam allowance at the neckline and turn the piece right side out. Place one of the front jacket pieces right sides together with the back piece. Backstitch across the shoulder. Repeat to sew the other front piece to the back.

5 The size and shape of the sleeve allows for three pleats, one on either side of the shoulder seam and one in the centre to line up with the shoulder seam. Mark the top centre of each sleeve by folding it in half width-wise and pinching to make a small crease, or make a mark with a fabric pen.

6 Place one sleeve and the jacket right sides together, matching the top of the sleeve with the edge of the armhole. Use backstitch to start sewing the sleeve into the armhole, taking a 3mm seam allowance. When you get towards the top of the sleeve, use the centre mark to help with pleat placement. Repeat to sew on the other sleeve.

7 Snip into the seam allowance of the two curved sides of the collar pieces, then fold them to the wrong side and secure the tabs with a glue pen. Backstitch around both edges. Do not fold in the seam allowance along the top of the collar, as you will use this to stitch the collar to the neckline.

8 Place one collar at the neckline, pointing upwards, so that the right side of the shirt and the wrong side of the collar are facing you. Match the seam line of the collar with the edge of the neckline, then backstitch along the seam allowance making sure that you catch the neckline in the stitches to sew the pieces together. Then fold the collar down the right way. Repeat with the other collar piece on the other front.
