Place wrap over one shoulder and under the other, with the wrap centered and spread across the child's body.  Make sure the child is "well-seated" in the wrap.  Make sure the wrap is spread over the shoulder.

Spread the fabric across your child, and place end under opposite leg.  Bring end around front and place between knees, exchanging with the other end.

Bring the second end now under your arm, making sure the wrap is securely tightened.

Spread wrap over child's body, and bring around to the other side (you can spread it and bring it under the leg if you would like, as an alternative).

Take both ends, bounce and tighten, and tie a square knot.
