Sweater
A sweater is one of the most commonly knitted garments, and can be constructed in many ways: top-down, bottom-up, with raglan, set-in, or drop shoulder sleeves.
Explanation
The sweater is the flagship project for many knitters, and comes in countless variations of construction, pattern, and fit. You can choose between top-down or bottom-up construction, and between sleeve constructions like raglan, set-in sleeves, drop shoulder, or saddle shoulder. Choices around ease, yarn weight, and gauge affect both the look and how long the project takes. A sweater usually requires an accurate gauge swatch and size calculation, since incorrect gauge has the biggest impact on such a large garment.
