What is the difference between hand tied and machine weft?

The difference between hand tied weft and machine weft is that hand tied wefts are done by hand and are much thinner than machine wefts. Hand tied weft lay flat against your scalp to give you a more natural look and significantly reduce bulkiness. Hand tied wefts come in pieces of about 24" long, you get about five pieces per pack more or less, depending on the length of the hair. The hand tied wefts must be reinforced before cutting and must be sewn around the weft, not through the weft. You can do this either with a glue (nail or fabric glue works great) or by sewing the weft down before cutting. Machine wefts done by machine and have a thicker weft. They do not need to be reinforced or secured before cutting and you can sewn through the weft.
