The accent was done because I royally screwed up the tips. So I thought, "well let's see what I can do with this brush." I wanted to make it look like a paint brush had attacked my nails. I'd say I succeeded in doing so.
I just took the end of the brush and kept dabbing it over and over again until I reached my desired level of satisfaction.
So it's not always terrible if you mess up. Just start getting creative and you can almost always cover up mistakes!
