Intarsia
Intarsia is a colorwork technique where each color block is knitted with its own bobbin without floats, suited to large, isolated color areas or motifs.
Explanation
Intarsia is used when you want large, distinct blocks of color or shapes, such as a logo or picture, rather than a repeating small-scale pattern. Unlike Fair Isle, intarsia uses a separate bobbin or ball of yarn for each color area, and the strands are twisted around each other where colors meet to avoid holes. Because there are no floats on the wrong side, the fabric stays thinner and more elastic than Fair Isle, but the technique is traditionally worked flat rather than in the round, since you need to see and manage all the separate yarn balls.
