Well, for the first time, I brought some plates of wood, then I cut them with my saw in the right form.
Then I took a printed paper and used it dor the walls.
I fixed it on the wood with glue.
Then I fixed the walls of the house togather with my hot glue pistol.
Think if I tell all the details, I would take so much time.
I used foils for the windows.
I colored them with windowcolor.
For the floor I used PVC floor, which looked like a wooden floor.
The furniture are from Playmobil, don´t know if you have this in America, too.
It´s an old company from Germany.
