matching tattoo with the girl who has half of my heart -- my best friend (: [i'm the left!] here's an explanation of it:
Our Sisters Knot Celtic heart is a symbol of sisterhood and the strong, eternal bond we share with our sisters and friends. The intricate Celtic knot heart is an unbroken line symbolic of an everlasting love. The stylized triquetra or triple spiral, woven within the Celtic knot heart symbolizes the three stages of woman. The three stages of woman are maid, mother and wise woman.
