There are a few differences between Laced Hair Hand Tied Weft and Laced Hair Machine Sewn Weft, one
way is the way they are sewn Hand Tied is sewn thinner than Machine
(weft). Hand Tied also comes in 7 pre-cut rows, where you have to fold
over the hair to the length desired. We do not recommend
cutting the rows to desired size because it leads to unraveling of the
weft. Machine (weft) comes in one long row which you can cut to the size
you desire.
Hand Tied tends to lay flatter against the head.
Both can be sewn in by beading into the hair.
