Our cream colored, unsewn folded signatures are comprised of acid free, 70 lb. text paper. Each signature is made up of 8 folios or sheets that are folded in half. Each signature will total 32 pages - front and back. A set of six signatures will make a text block that is approximately 1/2" - 5/8" thick and have a total 192 pages - front and back. After text block is completed, see Hollander's Casing-in Instructions to attach a cover.
