I have to say that when I have tidied up and got rid of/hidden things, I feel a lot better. Only thing is it doesn't last long, I pull things out in a hurry and don't put them back. I blame it on lack of sewing time, I really only get Monday afternoon and occasionally Thursday afternoon and I'm retired!
When I got a new cleaner I kept the old one specially so I could keep it upstairs and clean the floor regularly! Hasn't worked. What I could really do with is down sizing on the sewing machines but they all seem to have a little job they do well and it is hard to part.
And to think I lasted 42 years with only one sewing machine, no overlocker, no coverstitch and a small desk in a corner. I chose the pattern, thread and fabric and that was it until the next project. No stockpiling of anything. I blame the internet!
