This is a right hand exercise using only the right hand thumb and index finger.
It is a little tricky at first as the movement collapses from the top to the bottom (lower) 6th string. In order to keep the exercise within the first year limitation, the thumb plays on the 6th string only.
*Keep in mind that we are working towards the Travis Style of picking and in that vein, you will use both the index and middle fingers on the upper three strings.
Please take your time with this going slowly and carefully. This will develop your ability to play more complex patterns with independence between the thumb and the index, middle, and ring fingers.
