The nicest part of having a sewing room is being able to shut the door and nobody sees the mess! Keeping your sewing areas clean will likely be more annoying then having your things throughout the house. How about storing your bins under your cutting table in the living room. A friend of mine made a skirt for her sewing table. She purchased some inexpensive fabric and used double sided tape to attach the skirt around the table. Nobody sees what is under the table that way, and its an added storage space.
