Abstract
A device for keeping a thread tightened and secured while weaving is provided. The thread is allowed to advance in order to make a stitch and further allows the thread to return to an original position so that it remains tensioned for the next stitch. The device is retractable so not only secures the thread but returns it so that it never loses tension. In addition, it has openings designed to allow resting a needle when not weaving.
