It's hard to say exactly how many you'll need, since not all coffee filters are exactly the same. I'll tell you one thing I did learn, though: orange and green needed more filtration than the others. I discovered this when I thought I was finished, and found a little bit of white stuff still floating in those two flavors. No problem, though: I just strained them again through one more coffee filter, and that took care of it. So if you find you haven't strained it thoroughly enough, the good news is: you can always fix that later. Then I poured one of the infusions into my strainer setup. I had to pour about a quarter of my infusion in, then wait for some of it to soak through, then pour another quarter in, until I was done. (If the strainer clogs with white gunk, use a spoon to scrape the white gunk out of the way.) In the end, you'll have about 8 ounces of Skittle infused vodka. Then I dumped the funnel and coffee filters into one of the bowls I'd used earlier for counting out Skittles, to catch drips as I carried it over to the sink. I washed everything out for re-using (except the coffee filters, of course -- those I just rinsed before disposing of,
