Help, I have mice!! These guys are really cute and easy to make. I found mice silhouettes I liked online, sized it appropriately and cut them out in black poster board. I attached them to the moulding with double-sided tape. We have ours climbing up a staircase, but they would be fun running over a kitchen back splash too.
My son loves these. He even added his stuffed kitty at the top of the stairs "watching" them.
