I have always had a soft spot for conjoined twins (and sideshow freaks in general) Blue Raspberry Designs (on etsy) has three different, equally beautiful sets. Perfect timing for Halloween! (and American Horror Story, one of my favorite shows!)
"The rainbow, a natural phenomenon noted for its beauty and mystical appearance, has been a favorite component of mythology throughout history. Rainbows are part of the myths of many cultures around the world. The Norse saw it as Bifrost; Judeo-Christian traditions see it as a covenant with God not to destroy the world by means of floodwater. Whether as a bridge to the heavens, messenger, archer’s bow, orserpent, the rainbow has been pressed into symbolic service for millennia. There is a myriad of beliefs concerning the rainbow. The complex diversity of rainbow myths are far-reaching, as are their inherent similarities."
