In 1921, Guccio Gucci bought his own shop on 7, Via della Vigna Nuova in Florence, "Azienda Individuale Guccio Gucci", where he sold imported leather luggage. He also opened a small workshop to have his own leather goods made by local craftsmen. Eventually, a larger workshop had to be acquired to house Gucci's 60 artisans. In 1935 the invasion of Ethiopia by Mussolini led the League of Nations to impose a trade embargo on Italy. Leather became scarce, pushing Guccio Gucci to introduce other fabrics in the composition of the products, such as raffia, wicker, wood, linen and, jute. The rombi motif, a Gucci signature, was created. The Gucci's developed a new tanning technique to produce "cuoio grasso", which became a Gucci trademark. In 1937, Gucci launched its handbags.
