i've used liquid foundation for a long time and i've tried a variety of methods of applying it. my preference? a blending sponge! i couldn't bring myself to spend $20 on the beautyblender, so thanks to a tip from meg, i picked up the sonia kashuk version at target. i've been using it for several months now and i LOVE IT. last week, i came across a nearly identical sponge for half the price through avon. i believe there is also one at ulta for about $5 too! the stippling method you use with these sponges blends makeup easily while eliminating visible lines and streaks. if you use liquid foundation, you should give one of these sponges a shot!
