Make your own harlequin shelves

With a simple twist, square box shelves take on a whole new life.

The secret’s in how you hang them – these are standard box shelves, simply turned on their corners to become trendy diamond shapes. Add a splash of colour if you dare.

You will need:

  • Castle Timbers hanging wall cubes (set of three)
  • Three squares of 3mm supawood cut to the size of the shelves
  • Wood primer
  • Dulux Pearlglo – Mexican Mint
  • Dulux Pearlglo – Harvest Fruits
  • Dulux Pearlglo – Signal Red
  • Short (15mm) wood nails
  • Hammer
  • Roller or medium 38mm paintbrush
  • Three slotted hangers with screws and wallplugs

Cutting list: 

You will need the 3mm supawood cut to match the size of the shelves, in this case:

  • 240 x 240mm
  • 270 x 270mm
  • 300 x 300mm


Prime the supawood squares with wood primer and leave to dry. Then give the boards a light sanding.

Step 1

Paint the three squares of supawood in Dulux Mexican Mint, Harvest Fruits and Signal Red respectively using a roller for a smooth finish. Do two or three coats of paint until you are happy with the covering. Leave to dry in between coats.

Step 2

Nail your backing boards to the floating shelves with a short wood nail into the four corners of each of the shelves.

Step 3

Attach a slotted hanger to the top corner of the backing board and make sure it’s centred correctly so each shelf hangs straight on the wall.

Step 4

Measure and mark where you’ll attach the shelves to the wall, allowing for a slight overlap at the corners so that the shelves form a unit. Drill the holes with a masonry bit and insert wall plugs and screws.

These diamond shelves add an elegant storage display for hand towels in bright colours for your guest bathroom.
