I used 2 bookcases I didn't need elsewhere for the ends, added brackets underneath to hold another piece of plywood for a shelf, then added another piece of 4 x 8 plywood on top with a piece of simple trim placed just a hair above the edge to hold my new to me cutting mat which is also 4 x 8. This way the trim will keep it from sliding though I doubt it will as heavy as it is. This cutting mat has a green side with markings and a black side with markings and is self-healing. I keep a small sewing machine at one end to attach long borders and bindings so there is a place to keep the quilt from hanging over the side or getting all bunched up. The shelf below holds my containers of fat qtrs and scraps, some stablizers and fabrics I'm using on a project so I don't accidently cut into it until the project is finished. Also keep my trash can underneath too so close enough when I need it but out of the way when I don't.
