"The waist ornament of the Viking Period apron from Humikkala, Masku, is made separately and sewn onto the upper edge of the fabric. Spun woollen yarn of several plies runs through the spirals of both the waist and hem decorations." Pretty sure this photograph is by the Flying Stitchman. (travellingtrainin...)
In 1996 someone found a Viking hoard at Westerklief on the former island of Wieringen, The Netherlands. The treasure contained Carolingian and Arab coins, bracelets and silver ingots, all buried in an earthenware pot. The coins date the treasure at around 850. Wieringen at that time was a part of Frisia. In 1997 some loose objects like coins and rings were found, in 1999 a second treasure , and in 2001 a third, all on the same tiny island.
