This graph paper is ideal for knitters to design and chart new patterns. The rectangular spaces reflect the actual shape of knitted stitches, allowing for a more realistic representation of the pattern. The 4:5 ratio indicates that 4 stitches are equal to 5 rows (40 stitches = 50 rows). There are 200 pages in this 8.5 x 11 inch notebook. Glossy cover. Not perforated.
