These carpets not only make traditional, old and old carpets usable again, but also by combining traditional and modern art together, they are very beautiful and have been able to attract the attention of the people of the world. Patchwork carpets or carpet collages are made from hand-woven carpets from different regions of Iran under the supervision of experienced hand-woven carpet masters and European designers.
