Penelon
Penelon is the fictional fabric featured in the Thunderbirds universe. Penelon was discovered by the noted fashion designer François Lemaire, who named it after his favourite model, Lady Penelope Creighton-Ward.
The fabric itself has extraordinary properties: Penelon can be made into any costume design, it never gets crushed, it can squeeze into a space the size of a match box and it can be fashioned to look like any other material.
The fabric was keenly sought after by François Lemaire's rivals, who bugged and kept his office under surveillance; hence it was top secret. After this was discovered by Lady Penelope she suggested holding the premiere of the new collection made entirely of Penelon on board the new aircraft Skythrust designed by the International Rescue scientific genius Brains.
