How to Cast On
Broken down in very simple terms, knitting is just a matter of transferring loops from one needle to another. To get started, you'll need to put loops on one needle, and that process of creating loops is called casting on.
There are several methods of casting on. Each has a unique purpose and produces a different edge. Try different methods to find the one most comfortable and suitable to your project. Two common cast-on methods are the long-tail cast on and the backwards loop cast on.
Unless otherwise noted, the initial slip knot you use to start casting on counts as a stitch in the pattern. So if the pattern requires you to cast on 100 stitches, the slip knot would be stitch 1 and then you would cast on an additional 99 stitches.
When casting on, do not pull the yarn too tightly against the needle. When you start knitting you will be inserting one needle into the stitch you cast on to the other needle. If the cast-on stitches are too tight this process can become difficult and frustrating.
