Follow print copy as to the location of headings, inside addresses, closings, and signatures, indenting in braille as they appear in print. Indented paragraphs in the body of the letter should start in the third cell, as all braille paragraphs do.
To block a heading, count the number of cells needed for the longest line. This line should end at the extreme right-hand margin. All other lines of the heading start in the same numbered cell as the longest line. Runover lines should be avoided in the heading and inside address—even if this means that the blocked lines of the heading start left of the middle of the page.
If there is not room to include the last line of the body of the letter as well as the complimentary closing, signature, writer's and typist's initials, and notice of enclosure on a braille page, take the last line of the body of the letter to a new page.
It is recommended that the closing and signature be brailled following the rules for attributions (see §17.5)—i.e., start each line in cell 5.
