Try looking at thrift stores or discount stores for teddy bears or other holiday animals. Put them through the wash, and most of them will look brand new. When they're dry, tie colorful ribbons around their necks. Next, collect various sizes of boxes from shoebox size down. Wrap them in colorful wrapping paper and tie pretty bows around them. Display these present boxes with the teddy bears for an adorable decorating scheme. Try gluing a box under a bear's arm, or have a bear sitting on a present.
Hang a few ornaments or a few strands of tinsel from a chandelier. You can add a few pieces of greenery too, tied on with ribbon.
Use acrylic paint and some seasonally shaped sponges that you can find in a craft store to decorate your windows. Colors like white, red, green, gold, or silver look very festive. This can be a fun project that kids might like to participate in too.
Christmas tree ornaments can be used in places other than just your tree. Try picking out several ornaments that are the same color and putting them in a small decorative bowl on your mantle or on an end table.
