Borum Eshøj språng hairnet at National Museum, Denmark

Found the Borum Eshøj språng hairnet image at the National Museum, Denmark's website: http://natmus.dk/historisk-viden/temaer/livet-i-oldtiden/hvordan-gik-de-klaedt/bronzealderens-dragter/kvindens-dragt-i-bronzealderen/

Part of the caption, translated by Google Translate, reads, "The woman from Borum Eshøj at Aarhus had a beautiful hairnet and a hat, which was merged into sprang technique, with the grave."

This same item is shown in Peter Collingwood's The Techniques of Sprang and described in the book as having ridges and multiple twists.
