The Mammen stitch (sometimes referred to as the Korgen stitch) has it’s name derived from lavish nalbinding works found from a high status man’s grave (ca 960-970 AD) discovered in 1868 in burial mound Mammen, Denmark. The stitch is a relatively basic but will easily help to expand the beginning nalbinder’s depth to their stitch repertoire and is similar to the Finnish stitch. The stitch is characterized by a double loop on the thumb and is designated using Hansen’s notation as either UOO/UUOO F2 for the Mammen variant or UOO/UUOO F1 for the Korgen. Additional information on the grave finds from Mammen can be found here: oldtiden.natmus.dk/udstillingen/vikingetiden/mammengraven/language/uk/.
