I sewed the regular bodice Lisbon + full length sleeves in size 4 graded to 6 hip and the bottom band is a size 6. I took 1cm off the neckband which gathers the fabric a little. I used 23mm olive green tortoiseshell buttons and the guide for 2cm buttons as my button foot creates too much space. I fused another layer of (light to medium woven) interfacing to the underneath and tore off after cutting the button holes. I had to zigzag stitch the other side of the buttonholes as the buttonhole foot stopped at the turn. I used ten buttons rather than the seven button guide. I ordered them on ebay (20 for £3.80). I topstitched the seams with a zigzag stitch which makes all the difference for a traditional cardigan appearance. The difficult part was topstitching each side of the arm seams, which join nicely to the side seam stitching, and the pressed-up seam allowance on the sleeve cuffs took some manoeuvring.
