I have a sweet carved bird on my bookcase. It looked like it needed a new home, so I built one!
chipboard cut with xacto knife, taped together
First layer of plaster mesh; punched hole for a twig;
glued roof to the house and tied it with a bow to keep in place while drying.
Another layer of plaster mesh; covered roof with Paperclay; added some paint
painted Paperclay flowers leftover from another project and glued to house; add another layer of paint
