As so, a large number of very attractive designs can be worked with no more knowledge of knitting than how to form knit stitches and purl stitches. It is a basic idea of such combinations that knit stitches, worked vertically, will tend to stand up away from purl stitches (forming ribs) and that purl stitches, worked horizontally, will tend to stand up away from knit stitches (forming ridges or welts). This way, one type of stitch is often used as a background for the other.
Cables, being worked usually with knit stitches against a purled background, constitute another illustration of this idea. In the purely embossed type of knit-purl pattern, the two types of stitches are scattered or grouped more or less evenly over the surface of the fabric, so that a subtle design is formed which neither "takes in" like ribbing nor "takes up" like welting.
This kind of pattern is usually an interchangeable stitch as far as gauge is concerned, and may be used in any garment calling for "plain knit ting" with great effect for you guys! Knit-purl combinations should be worked with solid colors. They are not suitable for yarns dyed in variegated color, as the alteration in color detracts from the pattern.
Nor are they usually suitable for stripes of contrasting colors, since the color change rows give a "wrong side" appearance to those stitches which are purled on the right side. Enough for today maybe, but not before showing you some examples with some delightful pictures! Also, be sure to practice, as we all know that practice makes perfect.
Happy knitting, and see you all next time!
