indoors, artificial light
Honestly, this manicure did not turn out as well as I would've liked, which I think is partly due to the fact that the reds I used are not perfectly opaque in one stroke over black. This meant I had to go over and over the lines I made to make sure that the red showed up vividly, and that compromised the cleanness of the design. I kind of saw this coming and would've tried it over white, but I knew that black would set the red and gold off so much better that I had to try it anyway.
That said, I cannot wait to do more Harry Potter manicures, and you'll probably be seeing them past the 15th, so be warned. :)
