The Muniment Room in Westminster Abbey houses a royal seal bag that is attached to a document dated to 26 November 1280, and used to protect a wax impression of the Great Seal of King Edward I of England (1239-1307, he reigned from 1272) The seal bag is made of wool with a linen lining, intarsia (inlaid) appliqué (with motifs surrounded by laid linen cord) for the main designs, and silk thread embroidery for the details. The embroidery is worked in split stitch.
