Leather jackets are crucial in any revolving wardrobe, storing immense trait values for self expression and representation of rebellion. Biker and punk subcultures created patches, although they have now expanded to western streetwear which adorns rock band logos, as well as eastern calligraphy from Asia. Patches can also be made from other materials like Felt or stitched embroidered PVC. Indigenous peoples also created Velcro and leather patches for Global Heritage Collections.
