The internet is not sure what you call a group of Mermaids - could it be a gossip, a pod or even a splash? Regardless, I have still been making more mermaid cards with the free Sheena Douglass stamp I got a while ago
They have proved very popular and have sold well!
I try to make each one different, using a variety of stamps, backgrounds and embellishments
Sometimes she has blond hair, others brown or red, but I always paint the mermaids tail with green & blue cosmic shimmer to make it stand out!
