I have to admit, I tend to decorate my home with whatever I run across. I don't adhere to any particular theme. For instance, I've used pretty fabric remnants for everything from dresser scarves to window treatments. I have a small, lace poncho over the bottom half of my bedroom window and assorted flowers twined around the brass headboard of my bed. I used leopard print, fuzzy fabric as a swag in my bathroom and as the cover for the tank.
I would not be opposed to using running ponies or Ferrari parts in my living room to jazz it up a bit. Really, whatever you like to look at can be used to decorate. Hood ornaments can be beautiful statues given the right base!
Look around you. Use your imagination. Can that old knitted shawl be recycled into a swag over the hall mirror?
