We cut the supports 16 in. long, but you can place the second shelf at whatever height you like. Screw the end supports to the walls at each end. Use drywall anchors if you can’t hit a stud. Then mark the position of the middle supports onto the top and bottom shelves with a square and drill 5/32-in. clearance holes through the shelves. Drive 1-5/8-in. screws through the shelf into the supports. You can apply this same concept to garage storage. See how to build double-decker garage storage shelves here.
If you bought this superb polished table in a store, it would cost you a fortune, but our detailed instructions will help you make one for less than $100. And it looks like highly polished stone, but no-one would know it’s actually made from concrete with a wooden base. Also, you can embellish the top with leaf prints, like the table shown here, or personalize it with glass or mosaic tiles or imprints of seashells.
