How beautifully the stones sit with the tweezers! ❤It is harder to work, but the result is special. With time it will be easier, you will get used to it. It also depends a lot on the cut of the stones. You can work in the "chess board" (put a stone, pause one, and put a stone, pause one) on the larger surfaces, then complete with the pen. The result is the same and you "rest" your hand while working with the pen.😉My opinion is to work on a little smaller spaces... But you do what you think is better, of course!😊
