This led me to imagine new earrings with a play of picots in the center.
I propose a little explanation about the thing in the middle.
This is to make two very long picots (the most difficult is to determine the length depending on the pattern).
The first long picot joined after passing a pearl.
The second picot is passed in the opposite direction in the bead and joint.
As I like this pattern, I added a second version in one of my earrings!
