The first three strings (low E, A, and D), have thick and springy ends; the three thinnest strings (G, B, and high E), do not have thick or springy ends. You may use either set of strings.

Insert the thick end of the string into the top of the bridge and thread it through until about 3 to 4 inches of the string stick out of the bottom.

Wrap the short end of the string around the long end of the string, creating a loop.

Pass the short end of the string through the loop (2 or 3 times for thick strings, 3 or 4 times for thin strings). Make sure the final pass leaves the string underneath the bridge.

Pull both ends of the string until the knot is tight.
