Supplementary weft technique is considered one of interesting
techniques for the archaeological complex textiles which were known in Egypt. This
technique may be considered the first try to produce ornamented textiles. There are
many resemblance appearances between this technique and other techniques, such as
embroidery technique or brocade, so there are many mistaken concepts in regard to this
weave. Also this technique is called as an extra or additional weft. This study aims to
show the main characteristics of the supplementary weft and explain differences and
resemblance appearances in this technique, by using of some recent means to exanimate
the weave structure exactly, such as Stereo microscope (SM), binocular microscope
(BM), and scanning electron microscope (SEM). The study introduced many important
results that lead to understand of ancient textiles, weave structures and their distinctive
characteristics.
