Batts are precut, whereas blankets are available in continuous rolls. Precut framing timbers, an innovation pioneered by Aladdin, was first offered by Sears in 1916. For wall framing, "stud" or "precut" sizes are available, and are commonly used. Lensbaby offers precut disks in various shapes that had been selected in a contest. This system used precut timber of mostly standard sizes (2"x4" and 2"x8") for framing. They were often later transferred into the precut openings provided in book-like photograph albums.
