What is the distinction between Machine Weft and hand tied Weft?
Hand tied wefts are those that are tied around a strong weaving thread, a process that is done by hand. World Hair Extensions only sells hand tied wefts because they are much thinner than machine wefts, which means they provide for a much more natural look. Machine wefts are much more bulky because they are made using sewing machines, a process that is less precise than when done by hand.
