The finials were bought at Hobby Lobby on clearance for around $15 for all of them. The big scroll iron thingy was bought at Kirkland's on clearance and with an extra 25% off and I estimate I paid about $6 for it. Finally, the star in the middle is actually our Christmas tree topper but we keep it up year round because it gives us that warm fuzzy feeling.
