My 5 year old helped me decide what to do to my nails today. She said she wanted me to make my nails look like skittles, lol. I liked the idea, but didn't want to do a normal skittle mani, so I got to looking around on youtube, google, and just did a few general searches for ideas. Enter my son with the Nook, and he was searching as well, lol. It's a Robin Moses design, the first 3 minutes or so of the video is her making a dotting tool, but she calls it "Shotgun Rainbow". Shotgun Rainbow
I don't use acrylic paints, and I didn't make a dotting tool, lol. But here is my version.
