What you need:
embroidery thread
scissors
Make it:
Cut several lengths of thread, keep in mind half this length will be the length of the tassel. To be make things simple, I just cut directly from the skein.
Tie a length of thread around the middle, this will be the thread to hang the tassel by.
Fold the thread in half to form the base tassel shape.
Wrap a length of thread around the top of the tassel and secure with a knot.
Trim the ends of the tassel to the same length.
