Abstract: A new fishing line spool holder for mounting a spool of fishing line on a fishing rod to permit winding of the fishing line on to a fishing reel. The inventive device includes an elongate spool shaft having proximal and distal ends which is designed for inserting through the bore of a spool of fishing line to rotatably mount the spool on the spool shaft. Coupled to the proximal end of the spool shaft, is a flexible base. A mounting member is coupled to the flexible base. The mounting member has a mounting channel that extends between its ends for receiving the shaft of a fishing rod therein. An elongate flexible strap has a hole through which extends the spool shaft so that the flexible base is positioned adjacent the second surface of the flexible strap. On each of the surfaces of the flexible strap is a coupling portion positioned towards opposite ends of the flexible strap.
