This is a tiny bit more technical. I set the right angle to start. The ladybug is my ashtray. using reclaimed wooden pallets, and a little help from my plant "roadie" The screws are pre drilled and metal L was used underneath. The angle was pencil scribed and the offcut is mounted along the back rail down to keep the shelf from sliding. 100% of cut to length wood was used, correct angle! And bragging along it is level to a glass of wine. The pink elephant is named "kisser" and helps me with the plants. Uploading from this phone has been an issue, VOTE here!
