Same here. My tidying always involves tossing a lot of stuff I don't need. Like, when I started accumulating quilting stuff around my SM, I decided to cull the files in an adjacent file cabinet (on which a 10-gallon aquarium is sitting, which would be a pain to move) to empty half a file drawer for fabrics and paper (quilt plans, SM manual, etc.).
I have boxes of fabric under the extended flap of my SM flap. I also have boxes of fabric under the dining table behind me, which I am eager to get rid of. I also found room for boxes of fabric on the top shelf of a walk-in closet by, again, culling out things I did not need or use anymore.
It's a long way from how I want it, but it's a start.
