sunlight
I only have one picture because I'm still trying to figure out the best way to get good lighting - the desk lamp I'm using isn't the best for nail pictures, though it works fine for normal uses, so I took this picture out the window. Maybe once I feel more at home, I won't feel like a loony if I wander around outside taking pictures of my hand. ;)
If you don't know how to do the splatter technique or have simply never tried it, I encourage you to find a tutorial. I find it quite easy compared to water marbling, so it's a good place to start, especially as all you'll need besides nail polish are a few household objects. Especially for a college student like myself, it's nice when you don't have to buy anything extra to do some cool nail art.
I had better post this and log off now, as I have Arabic at 1:10, and I don't want to be late on the first day! Hopefully I'll have time to post again soon.
