This is a headboard I made of tongue and groove panels. Hope you like it :)
Step 1: Framework
First, I made a frame of wooden studs. I used small brackets for extra support in the corners, better safe than sorry...
On the backside i placed rubber furniture pads to save the wall from any scratches.
Step 2: Nailing the Panel
Put the nail at a 45 angle on the tongue as the picture shows and work your way up.
Step 3: Safety brackets
To secure the head board and to not make it fall when you remove the bed, I used brackets at the bottom. Make sure you locate the studs behind the panel and mount the brackets there.
