Imagine, if you will, five skeins of yarn all clumped together in a tangled mess and you've been asked to untangle the clump. Looking at the clump some folks will automatically assume the job is impossible and will just throw it out without even trying. Some will make a feeble attempt and give up almost immediately. And some, like myself, will launch into the project with frenzied determination to solve the puzzle.
Converting a skein of yarn into a ball is advised by many before one attempts to start a project. As long as the skein is without snags, rolling up a ball of yarn is often an easy task. It's accomplished automatically and without any particular fanfare. With skill and a little imagination, all kinds of beautiful things can then be made.
