use the double space and get the body of the letter in the middle of the page. If it is a long letter, don't carry the matter so far down the page that you leave no room for the pen signature. Try to keep your right hand margin as regular as possible. Don't have an inch to spare on one line and three characters crowded in beyond the margin on the other. You will seldom succeed in getting the margin on the right hand side to look as regular as that on the left, but give careful attention to it and you will do good work in time. If you properly set your marginal stop you should have no difficulty in this respect.
Place "Yours truly" fairly in the middle of the page, at about 35 or 40, according to the suggestions of your teacher. Never arrange a letter so that you are under the necessity of carrying only a few words on to the second page. If that happens re-write the letter, so as either to finish the whole letter on one page, or carry over a sentence or two on to the following page.
In envelope addressing, write the name just below the middle of the envelope and the city and state well toward the bottom. If you are using a single case machine be sure not to get a double impression from the upper case characters. Open the flap of the envelope, if necessary, and arrange your paper guides so as to keep the envelope flat against the platen or roller.
