I started by patching and prepping the walls. My mom had already removed the wallpaper that was there.
Once the base coat was dry, I taped of the sections for each board and wood grained them. I let them dry, then taped of and did the next section.
Once the walls were wood grained to look like boards, I added the shading between the boards. I also added some knot holes and nails at the top and bottom of each board.

I followed the same technique for the doors, but also added the "Z" cross boards on the front and back of the door.

I love the way this door turned out. It sure shows how a little shading and highlights can give it dimension. Would you have guessed it's a flat door?
Once I got started, my dad said he wanted a mouse hole too. So, I added a little mouse hole and a mouse... actually, it's a little bigger than I'd like, so it's more of a cute little rat. Recently, I was there to paint the kitchen walls outside the bathroom to look like stone. I'll post more on that later.
