Additional steps must be taken to keep your paper wallet(s) safe even after it has been created.

Keep your paper wallet in a private and secure place. Stick it in a safe, or even in a bank vault if you feel uncomfortable leaving it around your house.

Keep multiple copies. No less than two copies of your paper wallet(s) should be created. More copies are better, but only when the additional copies are stored in different physical locations.

Water damage or fires could damage or destroy your paper wallet(s) and result in permanent loss of funds. Use a fireproof safe and laminate your paper wallet to add even more protection.
