For the 13th day of the month, the 13th prompt is "Something you want to buy." I cheated a little on this one, because I actually already bought it and applied it yesterday. This is quite possibly the most fun you can have with a 10 dollar bill:
The Sally Hansen Salon Effects are basically little strips of nail polish that you stick on your nails. Since I have short nails, I actually got 2 nails out of each strip, so I have a whole set ready for the next time I want to wear them. Supposedly they last 10 days, at which point you can just remove with nail polish remover. So the answer to the prompt is that something I would like to buy is another set of these suckers. I really like the "Frock Star" look. Another girl named JenPolishAholic has daily pictures on her flickr accout - she is wearing Frock Star and this is what hers looked like on the 10th day:
So there you have it. I could wish for a new car or a new purse or this technique or these shoes (among others), but all of those things require more disposable income that I'm willing/able to part with. Instead, I'll simply stick with Sally Hansen. If you need me, just look for the girl with the fancy nails.
