Cut out a window from an unfinished cardboard ornament from the craft store. Mine is 6-sided, but round would be way easier. Cut a piece of Styrofoam to fit inside as the base/floor. Paint the interior walls, then glue a piece of Christmas or other paper to the base for a floor. Hot glue tiny pieces of furniture (craft store for about $1.49) onto the floor. Mine included a desk and chair, hutch, grandfather clock, plus table and 2 chairs. I glued on a tiny piece of lace for a table mat, and cushions for the chairs. I glued a clear 4mm bead for a vase, and 3 seed beads for flowers. I also glued a tiny picture to a slightly larger background for a painting over the desk. Paint the outside of the ornament, glue a piece of greenery to the front bottom, and a strip of quilt batting to the opening edges. Smear on a little tacky glue and some glitter wherever you think it would look good.
