The edges between the various scenes are reinforced with gilded leather, imitating gold thread embroidery. This technique, according to the V&A catalogue, is also known from contemporary Scandinavian pieces.
The use of appliqué to quickly decorate a piece of cloth and/or present scenes from a particular story was wide-spread in medieval Europe, and often known as opus consutum. The technique was particularly popular before the wide-spread introduction of large tapestry-woven wall hangings. The technique may be compared with the appliqués made to this very day in the Street of the Tentmakers in Cairo, Egypt.
