I just finished quilting a tree skirt using Glide thread in the color Dijon which looks like a bright gold. It's got a nice sheen to it, similar to Sulky Rayon thread. It's a poly thread that comes on a large cone 5000 meters (5468 yd) for about $7. There are other shades of "golds" and "silvers" such as Sand, Light Copper, Cleopatra, Military Gold, Light Gray and Sterling. If you are wanting a metallic look without the hassle, you might consider trying it.
I got mine at Bobbin Central.
