I spent Friday night - all of it - trying to get my gel manicure off. Morgan told me that at the salon they just soak cotton balls in acetone and then wrap them in tin foil for 20 minutes before scraping off whatever's left with an orange stick...so I figured, hey, I can do that myself and save the money, right? As it turned out it was a little problematic, being as once one hand is befoiled it becomes pretty close to impossible to foil the other hand, and then once both hands are finished it becomes pretty close to impossible to do...anything.
Anyway, it eventually came off, and to my surprise my nails weren't completely destroyed underneath. Yay.
