Here's how to work Feathered Chain stitch.
Work from top to bottom. Bring your needle up at 1. Insert the needle again at 1 and bring it up at 2 below and at a slant. Make sure the thread is beneath the needle as in photograph 1. Pull the needle through. Next insert the needle at 3 (note that 1, 2, and 3 form a straight line), bring your needle up at 4 (level with 2). Take the needle back down at 4 and bring it up again at 3, make sure the thread is beneath the needle again (see photograph 3). Then take your needle down at 5 (note that 4, 3, and 5 also form a straight line) bring it out again at 6 level with 3 to start the next repeat. Continue is this way alternating from side to side. Finish the last chain with a small stitch.
