Katbran, I learned how to make a beaded tassel at summer camp when I was a kid...surprising how things come back to an ancient mind! Yes, basically it's one very long strand divided into sections. You tie the long strand onto your loop, leaving about 5-6 inches of a tail. Using a needle, thread the beads and pull the string all the way through. Push the beads up to the loop. Skipping the last bead in the row, which becomes your plug, you come up through the beads in each section and knot around the center loop of the tassel cap (had to make one out of the 14k wire). Repeat this until you have enough tassel strands to fit your cap or cone. Mine took 12 strands. Make sure that you measure each strand before you come up through the beads to secure. Mine are at 2.25", length is a personal preference and how many beads you have!! To finish the tassel, take your needle and tie several good knots around the exposed threads. You could use glue to secure, but I was afraid that might make the thread brittle. Pass the needle back through one strand of beads and clip the thread (just like passing back through a pearl after the last knot.) Clip the excess. Take your needle and thread it onto the tail. Tie a few more knots around the loop and then do the same, as before, passing through a few beads and trim the excess.
I am sure there must be a video on this somewhere, but I could only find how to make a thread tassel (Purranha, they look super EASY to make!!!). FYI Rio Grand sells a tassel making gizmo to use with thread. I didn't purchase, but it looks fairly simple to use.
The findings are from GemPacked/Bella. They have tons of designs, with diamonds and silver or CZs and silver.
