This has all been great advice. I practically mugged a facilities staff member at work when I saw his rolling tool box as it looks perfect for totting a machine. Poor man looked a little frightened, worried I was complaining about his spreading out his tools in my office. When I finally explained why I was asking a numb look came over his face, "oh, for sewing" he said. I suspect he has a sewer in his life, as he looked resigned, almost beaten. This was the face of a person who has watched some one disappear into a fabric store for hours at a time.
I am a fairly experienced sewer, and certainly can ride herd on my own machine and its desire to occasionally create rossettes of thread with bobbin thread. My goal will be to 1. Have that not happen, 2. Remember my polite words rather than the words I say alone in my sewing room when that happens!
