Selecting the Right Yarn

• Use a machine washable and dryable yarn for this project. Your golf club head covers will be outdoors a fair amount of time, so they'll need to be washed regularly. If you use a hand-wash-only yarn, then your covers will be dirty most of the time.
  
  This also isn't a project for luxury yarns. Stick with acrylic, cotton or superwash wool. Novelty yarns, like fun fur can also work, as long as they are machine washable.
  
  The amount of yarn you'll need varies with the weight of the yarn. Each head cover will use up to 150 grams of yarn, so plan accordingly.
  
  

Knit the Gauge Swatch

• This project is pretty forgiving as far as size is concerned, so you can skip this step without too much likelihood of disaster if you're an intermediate or advanced knitter with lots of experience knitting hats.
  
  For everyone else, a gauge swatch will keep you from making a golf club cover that is much too small or much too large. Experiment until you find the yarn and needle combination that gives you a fabric that is dense, but not stiff.
  
  Measure your swatch to get the number of stitches per inch (spi).
  
  

Generic Pattern

• Multiply your stitches per inch (spi) by 7.5. Round your total up or down so that you get a number divisible by four. This is the number of stitches to cast on.
  
  Knit in 2x2 ribbing (knit two, purl two) for 9 inches.
  
  Knit one row.
  
  Increase 8 stitches, evenly spaced, using your favorite increase method.
  
  Knit for 8 inches.
  
  Decrease as follows: knit one, knit two together until the end of the round.
  
  Cut and pull the yarn through the remaining stitches and pull tight.
  
  

Add Some Personality

• You can add stripes, possibly using the number of stripes to indicate the number of the golf club. Or you can knit your golf club head covers in a different color for each golf club. You can add cabling or color patterning, such as argyle or other fair isle designs. If you add a stitch pattern, such as seed stitch, knit a swatch to check your gauge and adjust your stitch count accordingly.
  
  The 8 inches of plain knitting are the easiest place to add a personal flourish.
  
  If you prefer, you can knit the entire golf head cover in ribbing.
  
  You can add a pom pom to the top, or use novelty yarn for the top portion.
