Podaegi

The podaegi (Korean: 포대기, also spelled podegi) is a Korean carrier with a medium to large rectangle of fabric hanging from a very long strap. Traditionally the rectangle is quilted for warmth and wraps around the mother’s torso, while the straps are wrapped snug under the baby’s bottom and tied around to the front to support and secure the baby on the mother’s back. Western interest in the podaegi style has led to new wrapping methods which do go over the shoulders, and to narrower “blankets”.
