Each fringe needs Seed Beads or just one seed bead per inch or so, sewing down the fringe to make sure your fringe is strong. Try to make your bead thread hidden inside the yarn. This adorns the fringe and also gives it body and a swing. The yarn left without adornment may break unless it is ribbon or novelty yarn. You may tie a knot at the bottom and ad a bead on the stronger novelty yarn fringes.
Also, you may want to make some seed bead fringe between the yarn fringe. It is all up to you, you are the designer! I fringe everything I make because the fringe design is just something I love on my art to wear clothing.
Adding fresh water pearls to one fringe creates a focal point. I sew down the fringe adding the pearls every inch or so depending what I am adorning.
My fringe twister is what I treasure more than most of my tools. It makes any project easy to do.
