There is a portrait of Bess of Hardwick, for example, that depicts her sleeves as being decorated with knotwork in redwork embroidery. Knotwork is closely related to, but not identical to Celtic knotwork, which has been a popular form of design in the Celtic countries and elsewhere since the early medieval period.
See also the TRC Needles entry on strapwork.
