I used very thin wood from Hobby lobby in the model area. I cut a thin piece off about 1/2 X 2 inch and used some thin wood sticks to look like 2 X 4's. It was for my new husbands book that I made him for his birthday of him and his brothers building a cabin in the woods. Will try to upload a few this week when I figure it out. It worked great. Also used the white sand as snow in a few of the pictures.
