Start with a 11” X 17” sheet of paper. Your address block, return address block, indicia or stamp must be in the top left-hand quadrant of the page.
Fold the sheet lengthwise in half perpendicular to the longest edge. Keep the folded edge on the right-hand side.
Fold in half again perpendicular to the longest edge. Keep this fold on the bottom.
Now you should have a folded mail piece with the dimensions of 5 ½ “ X 8 ½ “ Your address information should be right-side up with a single folded edge on the right-hand and bottom side.
