I will admit it took the 3rd try to finish this book, but boy am I glad I stuck with it. The first half is very slow and confusing. Please don't be put off. The 2nd half had me at the edge of my seat, what a ride!
For a while I've been having problems with streaks when applying foundation. I would have to buff out the streaks with 2 brushes, and that takes extra time. With the sponge it goes on perfectly. Just use a padding motion and its all done in 10 seconds!
