I'm the oldest of 4 kids. After me comes my sister, and then my two brothers. We're all 3 years apart, and as soon as my youngest brother turned 18 I started hollering at them all about us getting sibling tattoos. Of course, we've yet to reach a consensus.

One brother is on the fence, the other swears he'll never do it. Luckily, my sister, the only sibling more inked than I am, is all in... provided we find the right design, one of the perfect sister tattoos that captures who we are to each other. That, my friends, is a pretty tall order!

It's difficult enough when it's just you all on your lonesome getting a tattoo, but it's a whole added level of complication when you decide to get a matching or coordinating tattoo with someone you love. You want to be sure it's something you all love enough that you want to have it permanently inked into your flesh, and that's a serious commitment. That's why finding the perfect tattoo for you and your brother or your sister is so important.
