Instructions
Remove the stitches that hold the lining, cuff and leather together. Turn the cuff inside out and unpick the side stitching on the cuff so it will lay flat. Make chalk markings to indicate where the original seam allowance and stitching lines were for both the side seam and top seam.
Lay the old cuff on the knit fabric. Match the ribs in the knitting for the new cuff so they are all running vertically like the old cuff. Cut out the new cuff using the old cuff as a pattern.
Transfer the seam allowance and stitching markings to the new cuff with the chalk and seam gauge. Fold the new cuff in half so edges that will form the side seams are together. Sew the side seams with a small zigzag stitch following the original stitching lines and seam allowance.
Fold the two raw edges together to form a cuff with the seam allowance and stitching on the inside. Stretch the cuff over the end of the leather sleeve so the raw edges of the cuff line up with the end of the leather sleeve.
Stitch the cuff to the sleeve using a leather sewing machine needle and top-stitching thread. Fold the cuff down and turn the jacket sleeve inside out. Hand stitch the lining to the cuff so it covers the allowance.
