I have a whole room (spare bedroom) dedicated for quilting. A chest of draws full of patterns, tools, kits, etc. A double dresser with 3 large drawers where I have trays of smaller pieces of fabric sorted by color & laid out so that I can see all pieces as I do mostly applique. Under the bed are plastic storage containers with larger pieces sorted by color. Closet has washed & ironed fabric pieces on hangers, filing cabinet, rolling cabinet with drawers for threads, etc. Rolling cart for TV has drawers with notions, etc. & then my sewing machine cabinet has drawers & shelf for iron, etc.
I could not believe how much you could stash in one room until I had to remove everything to have carpeting restretched last year.
