I found a video online that did this design, and I made it my own. (: But I painted these awhile back, and they turned out nice I think (: try them yourself! Paint the bottom one color, and the top of the nail the other. With a small paintbrush, slowly develop the three arches. Be patient and take your time with it. With a pen, pencil, or toothpick dipped in polish, dot your nails, and you're done!
