These are the few pieces I made with my left over waxed cotton cord. They are RM7 a piece. However, a plain ring (without charm) is RM5 a piece.
I just purchased Black and Dark Brown cotton cords, so you can choose between the two colours :)
Sizes:-
Small - approximately 1.7 cm in diameter
Medium - approximately 2.3 cm in diameter
Large - approximately 2.5 cm in diameter
* Rings are slightly expandable
* Small charms look pretty good with these rings. I prefer the silver charms but it's a matter of preference, doncha think? :)
