Knit fabric is made of yarn loops linked together, while woven fabric is made of yarns crossing at right angles, warp and weft. That is why knit stretches, drapes softly, creases less and breathes, but it can curl at the edges and unravel. Woven fabric is more stable, stretches little and can fray when cut.
In garment making, knit needs knit needles, a stretch stitch and a different cutting technique. Wovens need finishing of the edges against fraying. The choice depends on the garment: knit for comfort and fit, woven for a fixed shape.
