15's are small. I don't think that's even a usual gauge... 16 is.

The larger the whole, the smaller the number. 1's are a huge gauge.

I *love* that gum piercing. I would love to have that done if my job permitted it. It's against company policy to have more than 2 holes in our ear lobes (I have my naval pierced also, but I don't expose my stomach while I'm at work...)

I think those flames look great. I love the coloring, and they're so unique. You see a lot of flames on people, but those are really different. I love them! Is that a lotus you have? (I have a lotus tattoo in that same area of my back).
