I'm fortunate to have a whole sewing room now, but before we moved I shared space in our living room which forced me to get organized. My tip resolves around "Where do you put all your needles and fabric markers and buttons and....?"
My needles, fabric marker, scissors, small plastic cutting boards, rippers, etc... all living in a bathroom bag. A lot of people sew their own, but I had a spare one in the house that I never travelled with and it worked perflectly. Lots of pockets, durable and could be hung by my machine for easy access.

I've assigned everything a pocket that it belongs in. Unless my husband touches it, I can always find what I need! My buttons, snaps, embroidery thread and misc all living in a small plastic box with lots of compartments.
Good luck organizing!
