Kreinik had a great post on their blog recently. It talked about intentionally fraying the ends of their threads to make tassels.
The directions had instructions on how to create a fusible tassel using their iron-on threads. Although the instructions are designed to fuse onto paper, you could also do this onto fabric or canvas.
However, as the picture shows, you can also fray any kreinik thread and use it to make delightful tassels.
If you will be sewing on the tassels, make the tassels first, then fray the ends. Then sew the top on so the ends are free (as in the picture). By making the tassel before you fray the ends the top will be tight and easy to attach.
Isn’t this a cool idea?
