This is the first thing you must learn to start any knitting project. Depending on the pattern you are following, it will ask you for a certain number of cast-on stitches to begin the work. This will correspond to the size of the garment or accessory. Depending on whether you want to make the work longer or shorter, you will need to cast on more or fewer stitches. There are different techniques for casting on stitches on two needles, but we will teach you the simplest one, achieving the same result. The important thing is to practice a lot and not be afraid to undo if you don't get it right the first time.
