Embellishments
There are many types of ornamental embellishments that can modify the overall look of the sweater.
Collars and lapels are perhaps the most visually obvious embellishments. They frame the face, neck and shoulders, and complement the neckline and armhole lines.
The choice of closures is an important practical consideration and can also help define the sweater's style. Buttons and zippers are the most common choices for sweaters, but frogs, ties and belts are also seen.
Shoulder pads and other shaping devices are uncommon, but can be included to define a particular silhouette.
The fabric of the sweater can be ornamented with various textures, such as gathers, ruffles, pleats, ruching and shirring. Ornamental patterns can be added using beads, buttons, sequins, bobbles, ribbons and knots, as well as appliqué or cordwork. Overstitching (also known as Swiss darning) and other embroidery techniques allow for many visual effects that cannot be made with normal knitting, e.g., a circle of successively interlocking stitches.
