Q: What size French wire (bullion) will I need for my project?
A:French Wire can make a beautiful necklace really shine. The size wire you need varies with what kind of thread you are using. The fine wire should be used with thread size .50mm and finer. Medium calls for .65mm and finer. Heavy can handle threads up to .70mm and Super Heavy is for anything bigger than that. You will find thread diameters on most thread packaging.
