Firm, stable knits. These stretch very little and are handled similarly to woven fabrics. These include double knits and Raschel knits, a novelty knit recognized by lacy, stable construction. Lightweight single knits. They have lengthwise ribs on the right side, horizontal rows on the reverse side and moderate stretch.
Examples are jerseys and tricot knits.
These are lightweight, drapable and have a fair amount of crosswise stretch. They do not curl at the edges, but can run on the crosswise edge. Interlock knits are heavier, thicker, and easier to sew than jersey knits. These may be single or double knits. Examples include knitted terry and velour, sweater knits, and sweatshirt fleece.
