The drop-shoulder style sweater pattern is the simplest one of any sleeve style. The body of the sweater is a simple rectangle. The sleeves also have a shape of a rectangle or are narrowed towards the wrist.
The actual length of the sleeve is shorter than a measurement from the wrist to the shoulder. This way the upper edge of the sleeve doesn't reach the actual shoulder line.
To assemble a drop-sleeve pullover you will need to join the shoulders of the front and the back parts first. Then taking the shoulder seams as a middle point for the top of the sleeves, sew the sleeves to the body.
As an alternative, the sleeves may be picked up along the side edge, and knit or crochet down towards the wrist.
As an example we will use a few measurements from the Make a Garment page. The necessary measurements to design this sweater pattern are:
1) Back and Front (highlighted in yellow).
AB = Back Length = BL = 56 cm
BC = 1/2 (Bust Circumference OR Hip Circumference) + 1 cm = 1/2 (BS/2 or HC/2) + 1 cm. Between BC/2 and HC/2 a greater one has to be chosen. Hence: BC = 1/2 (BS/2 or HC/2) + 1 cm = 1/2 x 50cm + 1 cm = 26 cm.
Front neck line:
AK = (NC/2) /3 = 18 / 3 = 6 cm.
AF = (NC/2) /3 + 2cm = 18 / 3 + 2cm = 8 cm. Connect points F and K with a smooth curve.
Back neck line: AK = (NC/2) /3 = 18 / 3 = 6 cm.
2) The Sleeves (highlighted in white).
KL = Arm length + Neck-shoulder length = AL + NSL = 56cm
+ 13cm = 69cm.
DN = Bust circumference + 5 cm = BS/3 + 5cm = 48cm/3 + 5cm = 21cm.
There are a few good things about a drop shoulders sweater:
At the same time using a pattern with the drop shoulders, you should take into account that the drop-shoulders garments for the most cases require loose-fitting to make them comfortable.
Sometimes it gives a garment over sized look and makes you look broader than you actually are.
But once you know about this design feature, your creativity can change it to compliment your body instead. Like in this Cardigan Sweater for example.
