How to build a bed headboard

Background

This is a decoration that mounts to the wall behind a bed. I am not sure what to call it so I called it a bed headboard.

Parts
1. Molding pieces.

Instructions
1. Cut one piece longer at a length "A" equal to the distance from the level of the boxspring to the desired highest point. For example, A=36".
2. Cut 2 pieces a length "B" shorter than the first. For example, B=30".
3. Cut 2 pieces a length "B" shorter than the second. For example, A=24".
4. Attach a small square molding piece on top of each length of molding. I used small staples that secure the square to the long piece.
5. Paint all pieces as desired.
6. Hang the pieces in triangle fashion as shown below.
