My one is called my sewing room which has the largest amount of my stuff in it. Then I got a serger and set it up in the other small room that has been called Jeremy's room, the spare room, office and now its called the serger room. My grandkids know which is which so when we are cleaning I can tell them which room to put things in and they know where. I'm sure there are lots of reasons people call them different things rather its business, personal or a matter of preference. Just like some people name their machines or cars. I call my machines, the Viking, the Kenmore or the serger. No names needed.
