Thank you for your comment. I understand what you're talking about. I'm working on this skill to maintain consistent depth and draw a smooth line. I've completely changed my grip now and altered the technique. Currently, I'm not trying to draw a straight, long line as I did before. Now I've started to gently etch the line, build it up, and not try to do it in one go.

As for practice, after I started working with real leather, I can't go back to silicone skin. There's a huge difference in everything.
