And afterwards Aminita linked me to a video of someone doing an intricate design. I thought, "Well, that looks really hard to do left-handed using fingernail polish, but I do have some white polish that will contrast well with the black-glitter polish I already put on ... "
So basically, scope creep all the way. The right hand (which I had to do left-handed) is the same basic design but perceptibly sloppier, and it's not particularly well-done on either. But hey! Fingernail polish! I haven't painted my nails in many years, and never tried to put a design on them before. Kinda fun. :)
