A linear lace of two or three lines of hairs is fixed to a vinyl sheet. The single weft of wig hair is tied to the linear lace with a binding line. The wig is light in weight due to a single line of weft and the direction of curl can be easily changed. The weft of narrow width will not damage the scalp and suits well with the hair of the wearer.
