Bookshelf table made from an old spool...chop in half, put on walls as cute table/booth things? Depending on style/colour, etc! GREAT!
Cable spool bookcase, using wooden dowel rods for separators and attached wheels for moving around - great storage for all my craft books... but I can also see fabric and other fun stuff being stored! [call your local electric or cable company and ask for their empty spools - they come in assorted sizes... that's how I got mine!]
From Old Cable Spool To New Library Table - This would be fun. I envision a poof on top instead of a flat surface - rolling library with seat!
