The development of Mangas Original took four years of research, in which GAN had to find the tools and create the complex work method that allows the weaving of these pieces on a manual loom, despite their changing textures, threads, and widths.

Patricia Urquiola took as aesthetic reference the classic knitted wool sweater, to design a collection with lots of volume that could combine different textures. Some rug models have a very elongated shape and large dimensions, others are of medium or small size. All of them can be combined as if they were modular pieces. In addition, they can also be hung on the wall as a tapestry, and in the case of larger pieces, some can cover part of the floor and the wall at the same time.

The Largas is a long runner-type rug from the Mangas Original collection, woven in its entirety on a manual loom using 17 different designs and textures, arranged as stripes with lots of volume and a rich variety of colors. It can be used in combination with the mini models of this collection to create an even longer composition. Its shape resembles the sleeve of a chunky sweater ("mangas" means sleeves in Spanish).
