One of my resolutions for 2015 is to save some serious money. That involves getting less manicures. In NYC it's harder than it sounds, as there seems to be as many nails shops as there are Starbucks. I am one of those weird people that actually enjoy doing my own nails at home (mostly so I can watch Law & Order re-runs while they dry). Sharing with you a DIY navy triangle half-moon I did a couple months ago:
Obviously my lines aren't perfectly straight and there's traces of polish left on some cuticles, but those are definitely flaws I can get behind if it saves me $30! To achieve these, I did not use tape. Just lightly painted one diagonal at a time, then filled in the top. Give it a try, it's definitely easier than it looks and got tons of compliments despite the little flaws!
