This video is about professional/business letter folding and mailing. Before starting this process your hands should be clean and dry so as not to ruin the look of the letter. To fold the letter correctly, you must take the bottom 1/3 of the letter and fold it upwards towards the letterhead - it should be folded about halfway to the top. Then crease the fold. Next you fold the top down and crease that fold also. To mail, you must place the lettehead, head down, face forward into the envelope. This is done so that when the receipient of the letter removes the it from the enveope the first flap to be opened will show the letterhead.
