Finally, after many days of trial and error, I managed to finish the carnelian necklace. However the biggest problem was to find a thread in the right color and right size. I combined Perle Iris thread %100 Egyptian cotton, beautiful variegated amber brown color and DMC solid amber color.
The thickness and the color of the thread is very ideal for my project.
I tatted with the natural carnelian and delica beads.
The result is pleasing.
