Black and white nails- I wish I had the patience to do this right before Gavin is born. Newborns see most clearly black and white. I did a French manicure reversed black and white with Kennedy maybe I will do one of these with Gavin:)
Not sure about blue nails, but maybe I'll give it a try anyway. Essie Summer 2012 Collection - 'Bikini So Teeny' Nail Polish: really cute color that looks similar to Lapis of Luxury from but I will have to give this one a go as well.
Always choose best nail polish brands, since it is more durable. After all, considering the time and you've put into creating your nail art stamping, you want it to last for long time! also, best nail polish colors usually.
Put water in a bowl, drop random colors of nail polish in and swirl with toothpick. put petroleum jelly on your fingers so the polish only sticks on nails not your fingers. Stick fingers in bowl, nail polish should float on top of water.
