Refresh your fez with a high-quality replacement tassel, designed for easy installation and a distinctive new look.  To install, tie a very thin string or heavy thread to the existing tassel cord inside your fez. Remove the safety pin, then gently pull the cord outward, guiding the string through the opening. Untie the old tassel and attach the new tassel cord to the string. Carefully pull the string back through to the inside, then secure the new cord with the safety pin.
