Machine embroidery thread is for sewing thread to put into sewing machine to do embroidery stitching. We have only 4 different colors of metallic and mix color embroidery thread. It is 25 gram per spool. It is finer than normal polyester sewing thread. Other than for machine embroidery, this thread is very good to be used to make tassel earring because of the material very smooth and near to silk.
