These instructions are designed to be useful to a range of knitting ability levels.
Somebody who has never picked up a set of needles should be able to follow these steps sequentially to learn every element necessary to complete the scarf.
A more moderately experienced knitter may already know the knit and purl stitches, but wants to learn the cable stitch, for example. They can follow the pattern (as given below) and skip ahead to step five to reference instructions for cables.
The time it takes you to finish the scarf will vary depending on your ability level as well as how long you'd like to make the scarf. Keep in mind that for most, knitting is a hobby to unwind--see it as a marathon, not a sprint!
