Systems and methods of modifying a body of fabric

An adjustable fabric length system for adjusting a length of fabric, said system comprising:

• a fabric body having at least one edge portion;
• a plurality of extension pieces of fabric, each extension piece having an inner edge portion and an opposed outer edge portion, said plurality of extension pieces sewn together with one another and the fabric body in an edge portion to edge portion arrangement such that the plurality of extension pieces extend distally away from the at least one edge portion of the fabric body, each said extension piece being individually sewn to an adjacent said extension piece or the at least one edge portion with at least one release thread;
• and
• at least one tab operably associated with the at least one release thread of each of the plurality of extension pieces, said at least one tab releasably affixed to a respective said extension piece to cover an end of the at least one release thread and prevent the at least one release thread from being inadvertently pulled,
• wherein the length of fabric is adjusted by pulling or separating the at least one tab away from a selected said extension piece to uncover the at least one release thread associated with the selected said extension piece and pulling the at least one release thread uncovered to release and separate the selected said extension piece from the fabric body or the outer edge portion of a proximally arranged said extension piece.
