Natalia Volf

Hi all, I'm Natalia, 22y/o from Israel, happy to join this cool looking forum! Hoping to get some answers regarding my first (and big) tattoo I'm planning for the past 6 years. :o My main question for now is the location of my tattoo. It will be about 20*15 cm, all black, and I'm so uncertain of its placing. Currently I'm wobbling between doing in on my thigh right above the knee and between the shoulder blades. On one hand, I'm afraid that the thigh tattoo will get deformed and ugly though the years as almost any woman will shift her weight, and on the other hand, I want that tattoo to be visible by myself. maybe any other placement idea? Attached my wanted tattoo idea.
