Most square shape and lifting problems trace back to one filing angle or one prep step. This map finds it — follow the symptom, apply the fix, without guessing or changing five things at once.

With over 15 years of hands-on experience and a first-place win at an international nail competition in Warsaw, Yuliia teaches the way she wished someone had taught her — two real clients, every decision explained, timers on screen. Square is the shape that reveals every mistake. This course shows you exactly how to avoid them.
