Lay the string parallel to the guitar's neck and directly over the appropriate tuning peg.

Measure a "three finger's length" (about 1.5") on the string passed the tuning peg.

Make a sharp bend in the string at where you measured 1.5" passed the tuning peg.

Turn the tuning peg until the string hole faces perpendicular to the guitar's neck.

Feed the bent string into the tuning peg until the bend meets the tuning post.
