Well, as often is the case...what I made is not what I planned. I still haven't made the pendant but made another hair snap. However, I am so pleased with the outcome.
Where I would normally use embroidery thread, I used the ribbon and wrapped this around the plastic ring. And the front of the ribbon hair snap, is what is usually on the back of the thread hair snaps. Confusing? I hope not.
The button on the back is also a new idea. I had used a small fabric flower but found, on the ones I made for my daughter, that after a while it looked a bit scruffy. The buttons look pretty and work well.
