fish scales! Or, since these are pink, aqua, and gold, mermaid scales! Isn’t that the cutest (and easiest) idea for mermaid party backdrop? For an under the sea party, you could just switch out the girlie colors for blues and greens; for a goldfish party, you could use blue and orange or gold. And of course if you just like this look you could use it with any theme – omg This is so creative!
