I've made a box where one of the sides is detachable. I think it's more fun to be able to take photos from all angles, and without the detachable wall I wouldn't be able to take photos of Pettson and Findus sitting on the bench looking out the window.
I've only made holes for the windows, because the doors are going to be fake - they won't be able to open.
The front wall is easy to open and close because I've used a cocktail stick and small holes to hold everything together when it's supposed to be closed.
I am using kindling as floorboards. I've bought them in Biltema (a Swedish chain of retail stores, specialising in tools, car supplies and leisure products) and they only cost 25kr for a large bag.
Findus has been helping carrying the boards.
Of course he had to show off in the window.
I've made the doors out of cardboard and some of the sticks from one of my placemats. Now they only need some white paint.
