To practice my tape techniques more, I decided to try a manicure using my thin striping tape (10 for $3 from China — eBay FTW). My pinky ended up a little clunky, and on my index finger you can actually see a few smudges from where I took too much polish off. Let that be a lesson in patience.
The always-lovely mint color is Annie's favorite, Essie Mint Candy Apple. This is a fairly straightforward manicure (three pieces of striping tape over a base color and top coat), but my one takeaway for you is this: Don't try to correct your mistake after you pull the tape too soon.
My layers were a bit too thick on my index finger, so the polish actually bled into the gap created by the tape. When I tried to go back to correct my mistake, I ended up taking too much polish off because in my rush, I forgot to sponge the excess acetone off the brush.
Moral of the story: Go slowly! Be precise when doing tape manicures, and be sure to use thin layers when polishing so the polish won't bleed.
