If the clutter in your sewing room is really bothering you and is something recent, maybe you need to see your physician, it can be symptomatic of other issues.
I read that Clutter can effect your personal health and is a gauge to your mental health, which makes sense to me. I suffer from depression (hormonal, seasonal.. etc) and when I am feeling depressed, I don't have the energy to do anything, except lose myself in my computer, which drives me nuts because I really hate clutter....
Here is a link to a great article:

But, when I am immersed in sewing projects I do leave things out where I can get to them, like the ironing board and cutting table.... still bothers me but is tolerable... ha ha
