Our cream colored, unsewn folded signatures are comprised of acid free, 70 lb. text paper. Each signature is made up of 4 folios or sheets that are folded in half. Each signature will total 16 pages - front and back. A set of six signatures will make a text block that is approximately 1/4" - 3/8" thick and have a total 96 pages - front and back. After text block is completed, see Hollander's Casing-in Instructions to attach a cover. Please note the thickness of a six signature text block will be half the thickness of our pre-sewn X-Large Text Block Journal.
