This is what our master bedroom looked like before (well this was a couple years ago, there were some minor changes but this was roughly what it looked like).
This is how I made the shiplap wall.
I headed to Home Depot and got the 4×8 underlayment boards that are about 3/16″ thick.
Here is the break down of the costs:
4 boards at $11.97 = 47.88
White paint = $23.00
Primer = $15.00
Other painting supplies = $15
So it could be less if you have the paint and supplies, the wood only cost about $50!
Using a table saw, we cut the planks 7.43 or 7 7/16 inch.
Once the paint was dry, it was time to put up the boards. Using a nail gun and finish nails we put up the boards onto the wall. We used a little piece of wood to measure the gaps to space them evenly.
This is my favorite spot in the room though, I just LOVE this corner!
