In 2013 Factum Arte has been commissioned to produce a new series of works for Algerian artist Rachid Koraichi.

Lettre bleue a ma mère is a vast tapestry of almost 4 meters in height produced in 2014 and included in the "Prayers" series. The series is dedicated to Rachid's mother and it is based on original drawings by the artist. His work is influenced by a fascination with signs and symbols, especially the Arabic calligraphic scripts, but also from a wide variety of other languages and cultures. The tapestry was unveiled at the October Gallery stand at Abu Dhabi Art 2014 in November. The tapestry has been realized with Blanca Nieto and Flanders Tapestries in Belgium.
