I have seen sparkly floss at Super Walmart. They call it Metallic or Light effects but not the brand Cosmo. DMC and J&P Coats brand.
another option you can consider are some of the specialty threads from superior like the Holographic ones. Some on line stores will give you a break on shipping for smalls like thread.
Brand names for some of these are Razzle Dazzle and Glitter from Superior
YLI makes one called candlelight
