About:
Scoubidou (craft-lace or scoobies) is a knotting craft primarily made for children. It originated in France, where it became a fad in the late 1950s and has remained popular ever since. It is named after the 1958 song of the same name by the French singer Sacha Distel. The material was so popular that many designers in France began using it to create furniture and decorative home accessories.
The most common type of yarn used in crafts is flat and comes in many colors, often called "wrapping yarn." Another type of scoubidou wire is flexible, round, and hollow, made of plasticized PVC tubing. They are sold in different colors, sizes, and types and are used to craft items by tying them together with knots. 
Due to their elasticity and hollow section, which allows them to sag and deform when pulled, they form tight, stable knots. They also allow weaving and can include many geometric shapes and designs. Simple objects are most often woven or braided, although more complex shapes and figures can also be created.
