That seems like a no-brainer, doesn’t it? Why would I knit something I don’t want to? Or something I don’t need? I’m more of a process knitter than a product knitter, so sometimes I knit for the love of doing it, or to learn something new that I’m curious about. Or to find out what a yarn looks or feels like knitted up. Even then, I usually want to make it useful. Swatches can be connected into blankets, bags, and so forth.
