The structure of this sweater follows a typical structure of a top-down drop shoulder sweater.
First the upper back is knitted flat before being placed on hold. The shoulder stitches are then picked up and the upper front sides are knitted one side at a time. The front is then joined along the neckline and the remainder of the upper front is knitted flat to the bottom of the armholes. At this point the front and back pieces are joined and the lower body is knitted in the round. The neckline is picked up and knitted in the round before the sleeves are picked up and knitted one at a time in the round.
I recommend knitting the neckband before knitting the sleeves to ensure the sleeves are knitted to the desired length but this is a personal choice and the neckband can be knitted last.

The sizes range from 1(XS) to 9 (5XL) which goes from 71 - 158 cm (28 - 62 inch) bust.

The recommended ease is a positive 20 cm (7.75 inches). The ease for the largest size is 20 cm (7.75 inches) from a 155 cm (61 inch) bust.

Whilst the recommended yarn is cotton from We Are Knitters, any yarn which meets gauge can be used. Cotton is recommended though as this sweater is designed with summer in mind!
