Saddle-Stitch booklets are several folded sheets of paper, bounded and stapled together, usually with 2 staples.
Because one folded sheet is 4 pages (counting front and back of the sheet), a Saddle-Stitched booklet must have a multiple of 4 pages,
including 2 for the cover pages. Saddle-Stitch is the most common and most affordable binding method.
Saddle Stitch is perfect for brochures, pamphlets, menus, magazines.
Depending on the quality you want to give your booklet, change the paper weight to be more or less dense.
Typically, a heavier paper gives a better feel/quality than a lighter paper booklet.
