I have added a really comprehensive webage on metal threads, which has a photograph of the metal thread set up against a ruler so you have a better idea of the size of the metal thread, making it easier for you to choose metal threads for your own embroidery.

I also have included pictures and descriptions of how the metal thread can be used in an embroidery.

You can link from the metal thread information page to the product pages by clicking on the name of the metal thread that is highlighted in blue.
