A fishing line guide is secured to a rod by a thread winding wound from a starting end which is tucked under a line guide to a tail end which is secured by heat fusion to an adjacent turn of the thread winding. The thread winding forms a single thread layer. In order to fuse the tail end to an adjacent turn of the thread winding, the thread is wound about the guide and rod and, with the unwound portion of the thread held taut, a heated rod is swept across the point where the thread leaves the rod to melt and sever the thread thereat while fusing the resultant tail end to the adjacent turn of the thread winding.
