OMG I USE THE SAME THING! lol. Anyways, don't use sponges, they soak up the foundation

... so basically, you are wasting it. Buy a brush, they recommend it at MAC, but you can even buy one at drug stores, ask them about "QUO". I got mine for $15. You can even apply it with your fingers, works really well too. Wrap a headband around your head, also buy some wipes, wipe it on your eyebrows and lips after apllying your foundation, as well as the hairline too! Baby wipes!
