Abstract

Certain embodiments of the invention include an apparatus for creating a line. Certain embodiments of an apparatus include two or more reels having an extendable and retractable cord. Pulling the two or more reels apart allows for the creation of a line of various sizes. In certain embodiments, the two reels share a single cord. In certain embodiments, a first reel has a first cord with a first attachment end that joins with another attachment end. Certain embodiments include a reel with a magnet, allowing attachment to a magnetic surface. Certain embodiments of the invention include a system for creating a line. In certain embodiments, the system includes an apparatus, and a pin having a magnet. Certain embodiments of the pin help to change the direction of the cord.
