Definition of Bouclé

Bouclé is a kind of novelty yarn. It is a yarn with a length of loops of similar size which can range from tiny circlets to large curls.

To make bouclé, at least two strands are combined, with the tension on one strand being much looser than the other as it is being plied, with the loose strand forming the loops and the other strand as the anchor. Bouclé can also refer to the fabric made from this type of yarn, especially fabric that maintains the looped appearance.
