Blend your 0.5 and 1.5 with a 1 guard and taper arm open. Go with the grain first to remove any excess bulk, then blend against the grain. Refine the fade by using the corner of the blade just to take out any darker areas without pushing the line up. Connect the #3 with the #1.5 using the #2 guard open. Go with and against the grain for a smooth finish.
