I usually see an image of what I want a particular yarn to be, by simply holding it and letting my mind wander, but that is where things actually become difficult. Now I need to play, okay, it is swatching, but I have never been good at creating swatches, I want to get on to making something not just make squares of stitching.
Sometimes I get into the process and realize that I like something else better, and either re-create my idea or create something completely new. Okay, this happens in many aspects of life; from everything like what to have for dinner of what I am wearing to that holiday party. Ideas constantly evolve. This is my reminder that nothing is a constant; the only thing that I can accurately predict is that everything will always change. I will admit, this keeps me from getting too attached to any one idea for very long, and I hope helps keep my work fresh. One can hope at least.
