The first method, commonly known as half-staffing, is performed when the flag is hoisted to the top of the flagpole, then lowered to the pole's one-third position. The other method is to attach a black ribbon to a flag that is permanently affixed to a staff. The ribbon itself is ten centimetres wide and it is attached to the mast so that the ends of the ribbon reach the bottom of the flag. During a funeral ceremony, the flag may be used to cover the coffins of government officials, soldiers, signatories of the Act of the Re-Establishment of the State of Lithuania, and persons designated by an act of the President; these flags are later folded and presented to the next of kin before interment. When flying the Lithuanian flag with other flags, the following is the correct order of precedence: The national flag, the historical (state) flag, flags of foreign states, the flag of the European Union, international NGOs, the presidential standard, military and government standards, county flags, city flags and any others. When foreign flags are used alongside the Lithuanian flag, the flags are sorted according to their countries' names in the Lithuanian language. The only exception is when the congress or meeting held in Lithuanian dictates a different language to be used for sorting. The European Union flag has been hoisted since Lithuania became a member of the organization. While not mentioned by name in the law, the flag of NATO can be used in Lithuania, since it belongs to that organization as well. It is also common to fly the flags of Estonia and Latvia during certain occasions, mainly the celebration of independence of the three Baltic states. The Law of the Republic of Lithuania on the National Flag and Other Flags governs the rules, use, protocol and manufacturing of the national and other flags used inside the country. As part of the flag protocol, the daily display of the Lithuanian flag is encouraged, but is strongly encouraged or legally required on the following days:  Apart from these days, the flag is flown at election polling sites. The national government, under Article 4, Section 7 of the flag law, is given the authority to call for the display of the national flag and to determine special conditions, such as marking for mourning. A naval ensign has been used by Lithuania starting in 1992. The ensign has a white background charged with a blue cross, with the national flag in the canton. The width of each cross is 1/7th of the total width of the ensign, with the ratio being 1:2.
