Letter Fold
Folding pattern in which the folds are parallel and in the same direction, so that a kind of spiral is produced. The letter fold is a parallel fold. Two or more panels of the same width of the folded signature are folded around one panel. When the signature is folded twice, there are three panels on each side (six pages); with a tri-fold, the result is four panels on each side (eight pages). To allow proper nesting of panels that fold in, inside panels are usually 1/32" to 1/8" smaller than outer panels with the inside end panel being the smallest.
Also known as a Spiral Fold, Tri Fold, Brochure Fold, Business Letter, C Fold, Roll Fold and Barrel Fold.

Famous quotes containing the words letter and/or fold:
“Love is the hardest thing in the world to write about. So simple. You’ve got to catch it through details, like the early morning sunlight hitting the gray tin of the rain spout in front of her house. The ringing of a telephone that sounds like Beethoven’s “Pastoral.” A letter scribbled on her office stationery that you carry around in your pocket because it smells of all the lilacs in Ohio.”
—Billy Wilder (b. 1906)
“Chores begin when your child can pick it up, put it away, fold it, sort it, or carry it out the door.”
—Jean Ross Peterson (20th century)
