Child sized necklace

Hi I have been making some jewellery for a friends wedding and am now doing some pendants for the bridesmaids.... does anyone know where I can get hold of a sterling silver snake chain necklace suitable for a 4 year old? I'm guessing maybe 14 inch? Maybe smaller...or would I have to make one up myself?
Thanks

The D for diamond childrens range I sell come with 14" chains
if that helps :)

Or you could chop off a bit from a longer chain (so you already have the ends and clasps) and resolder. You can then use the off cuts to make earrings :D
