  "description": "Anybody who has seen my gallery knows that I love using rainbows in my Personas.. I tried to keep these 2 designs simple, but pretty. “A BIG Rainbow for Easter” is actually “Rainbows for Easter” flipped over. When I flipped it as an experiment, I liked what I saw so much that I left it exactly as it was. So, if you use this one and you have a larger browser than I do, you might see more than one rainbow! Happy Easter! c0l1 \t\n\nAn original Holiday design by CollieSmile\n\nI would love to know what you think of this design or any of my others.
