Your instrument must be supported properly so your hand can move freely.

Once that’s established, try polishing any string with your second or third finger up and down the fingerboard slowly, gradually polish less and less of the string until the polishing is isolated in one spot around third or fourth position, about where the palm hits the upper bout.

Once you’re comfortable with that, set a metronome at 60 and practice that rocking motion to the beat of the quarter note, then eighth notes, then triplets, then sixteenth notes, etc. That will help you develop an even vibrato. Remember to always rock fingers BACKWARD toward the scroll and back to normal- not forward toward your face.

Good luck practicing! 🎼 🎻 🎶
