The before and after shots below are not very different. This is because I determined to follow the Cult of Tidying for this project, and so I devoted some hours to tidying the electronics and the yarn.
In the Before picture, therefore, we see the results of weeks of neglect, including a fair amount of opening the door, shoving things in, and then closing the door.
In the After(1) picture, we cannot see it, but all the yarn has been sorted into weights and stored vertically in the yarn bins. In many cases, it was also disentangled, rolled into balls, and even frogged and rolled before it was put away.
