My standard recipe, soaking 10 Skittles for every ounce of vodka. It doesn't really matter what type of vodka that you use (because it tastes like Skittles), but I typically use Smirnoff. I soak the Skittles overnight and shake them up at least 3 times during soaking. To strain the Skittles, I use the cheapest coffee filters. 2 filters at a time (stacked on top of each other), but changing them frequently as the gunk starts to collect at the bottom of the filter.
Skittles vodka... works great with rum too! Smooth, sweet and taste just like the Skittles. Can be imbibed straight, but if you add a mixer like Sprite, Ginger Ale, etc. then be careful because it just taste like a Skittles drink without the alcohol. It's REALLY good and you won't realize how much you're drinking.
