This is one of the easiest jeweleries i've ever made!
I saw a similar bracelet on another blog and wanted to make one for some of my sisters and for my self.
What you actually need to do is pretty simple and it;s just 3 steps!
1. You create this first piece by measuring your wrist.
2. You put the second piece in the middle of the wrist bracelet
3. The third piece needs to be able to come in and out of your finger easily.
Then you just attach everything using small rings.
The trick is you need to be careful with the length of the second part cause your hand needs to be able to move BUT you dont need it too long cause it will fall on the side of your hand all the time.
