I am an organized person by nature and abhor clutter, so my sewing room is pretty organized most of the time. I also use it as my office, so tend to dump things in there during the week and it becomes more cluttered by the weekend. Today, I need to go in and put away fabric I bought this week while traveling for work, shelve library books I brought home, go through the mail for things that need to be taken care of and file the rest, that sort of stuff. It usually takes 15-30 minutes and then I'm back to a room I can function in.
It is kind of decorated. I have a stained glass lamp and several original paintings that I bought over the years and love. I want it to be a room I want to spend time in, but not too much decorating so that there is more room for functional.
I am learning to ignore the clutter during a project and just throw threads on the floor and push things out of the way to keep sewing. But when I am done, the OCD part of me takes over and I have to clean it back up so I can start over.
