My sewing room is just crammed full

I'm working at getting it better organized again, but it's just a small bedroom (10x12??). I can open the door and have the width of the door to walk through to the end. Otherwise to get to some stuff I have to pull the stacks of boxes out or move the wheeled storage shelves.
When I'm not so ashamed of it I will post a picture. The sad thing is I have already given away roughly 8 full black plastic bags of yardage/non-quilting stuff. I've been quilting since the 70s so it's decades of accumulation.
