Cut a two to three inch square of foamcore board or bookboard/chipboard I used precut three inch chipboard squares from a scrapbook store. Set your chosen house in place towards the back of the square, and mark its base outline.
Paint the base. Mark the position for a sidewalk to the front door and paint this with acrylic paints. When the sidewalk is dry, paint the rest of the base (except for the area marked out for the house) with white acrylic paint. While that paint is drying sprinkle a bit of fine sand into the paint to give it a snow texture. Paint over the sane with a second coat. Set aside to dry.
Spread some glue on the base tabs of the house and glue it in place. Cut out the fencing trim (I used trim scissors to get the scallops) and lay it out on the base,1/4 inch in from the edge. Fold it to fit, trim if necessary. Apply a thin bead of glue to the bottom of the fence and glue it in place on the landscape. Add paint, glitter or Scenic Snow to cover bare areas.
Making the Trees You can use scraps of lycopodium moss (princes pine) as shown for the 1:144 scale Christmas scenes. On the accessories sheet (and the three gables sheet) I have provided small green circles to make trees. Cut them out and use a pin to pierce a hole in the center of all but the smallest circle. Thread them in order of size, largest first, onto a round toothpick. Cut to the center of each circle using sharp scissors, and use tweezers to put overlap the cut edges until the circle dips to form a cone. Glue the top cut edge to the bottom edge to hold the cone in place. Cut into the center of the smallest circle and glue the overlapped edges to form a tight cone. Glue the cone onto the pointed end of the toothpick to make the top of the miniature tree. Glue the circles to the trunk if necessary. Dry brush the finished tree with white paint to make a snow effect.
