Simple built-in to create a mudroom and/or storage anywhere from an entry, to kids room or in a laundry room by adding shelves or a deeper bench for sitting. Put drawers under bench or have the seat lift up to store things.
Use a magnetic board and favor tins to organize small things vertically. I'd like to put my spices in the tins, to save space in the kitchen! This link includes lots of great craft storage ideas, including using closet organizers for craft supplies.
