Recently, my boyfriend treated me to a manicure at the Aveda salon. The manicurist was wonderful--meticulous and efficient--so I made sure to pay attention so that I could replicate the manicure for myself at home. Of course, I was familiar with most of the process, except for one thing--I noticed the manicurist didn't shake the nail polish bottle. Instead, she rolled it between her palms.

That got me to thinking... what else is keeping me from getting the perfect at-home manicure?
