The end pins are packaged as a kit and are useful in performing a method of repairing an umbrella including the steps of withdrawing an end pin from a supply of end pins provided by the kit and inserting the shank of the withdrawn end pin through the cover of the umbrella or an attaching loop and into a stem of the umbrella, which stem is in need of repair. The shank passes into interference engagement with the stem into which it is inserted. The end pin has an end tip of larger diameter than the shank and the inserting step is continued until the end tip attains overlapping engagement with the umbrella cover or the attaching loop.
