Different stitches and stitch combinations affect the properties of knitted fabric. Individual stitches look differently; knit stitches look like “V”‘s stacked vertically, whereas purl stitches look like a wavy horizontal line across the fabric. Patterns and pictures can be created using colors in knitted fabrics by using stitches as “pixels”; however, such pixels are usually rectangular, rather than square. Individual stitches, or rows of stitches, may be made taller by drawing more yarn into the new loop (an elongated stitch), which is the basis for uneven knitting: a row of tall stitches may alternate with one or more rows of short stitches for an interesting visual effect. Short and tall stitches may also alternate within a row, forming a fish-like oval pattern.
