Tassels by the YardAwesome! I can never find these kinds of trims in the color I want and now I can make my own. Probably need to do a tassel party to get help to do the amount of yards I need tho. :) :-D
For that bead I simply wrapped - with needle and thread - going through the hole. Use large hole wooden beads - and then use a bead reamer to clean the holes, smooth them and make them a bit bigger. A bit of beeswax rubbed on the bead will help the initial threads to stay in place.
There is a more complicated 'proper' method of passementerie wrapping which is used for larger tassels, but it is fiddly and most people I teach find 'sewing' through the hole easiest for small beads.
