Just like opinions the definition of clutter varies. I walk into my friends house and her whole house is her sewing area. Her definition and I have to agree is when others use her sewing area for a "catch all' like (as she calls drinking objects) beverage vessels and food containers that should be removed back to the kitchen from whence it came. Bath towels to the bathroom, dropped clothing to the hamper or bedroom. that is clutter. I have to agree with her. there is a difference between clutter and hoarding (a whole "nutha" issue).
