When knitting, what is the term "casting on" referring to?

The term "casting on" refers to the first row of stitches created when beginning a knitting project. This fundamental step establishes the initial foundation on which subsequent rows will be built. Casting on involves creating a series of loops that will eventually form the edge of the knitted piece, allowing subsequent knitting techniques to be applied.

Understanding this concept is crucial for knitters, as it not only defines the starting point of any knitting project but also affects the overall structure and appearance of the finished work. The technique used for casting on can vary, with different methods yielding different edge characteristics, which can be important based on the desired outcome of the project.
