Well somebody asked, so here you go. A step by step guide to building shacks.
So then you tape the two pieces together to make your rectangle. Then I hit the inside corners with some hot glue to help it keep its shape and make it a little sturdier.
Here is the back side of the building and as you can see, I didn't glue the first set of planks on. Instead I just glued the small strips on the entire back of the shack and it makes it look like the side, but in better shape. I just use the ribs of the cardboard as a guide since they are spaced at 1/4" also.
Then I added another bit to the roof. This piece is going to be tar paper. It was the paper from a piece of foam board paper that was in my scrap box. I picked at the edges a bit to give it that torn look, and then scraped off any remaining foam and glued it rough side up.
At this point I think I have approximately an hour and a half (at the most) into the piece. Tomorrow I will flock the base and seal that, then paint it brown. After that, maybe this weekend I will paint it. I'll do a part 2 in case anyone is interested in seeing it through to completion.
