An authentic Torah scroll is a mind-boggling masterpiece of labor and skill. Comprising between 62 and 84 sheets of parchment-cured, tanned, scraped and prepared according to exacting Torah law specifications-and containing exactly 304,805 letters, the resulting handwritten scroll takes many months to complete. An expert pious scribe carefully inks each letter with a feather quill, under the intricate calligraphic guidelines of Ktav Ashurit (Ashurite Script). The sheets of parchment are then sewn together with sinews to form one long scroll. While most Torah scrolls stand around two feet in height and weigh 20-25 pounds, some are huge and quite heavy, while others are doll-sized and lightweight.
