You can use any shape. It doesn't have to be a bunny. Just trace a shape or cookie cutter. This would be cute for any holiday, just use an appropriate cookie cutter to trace and cut out the shape, then whatever yarn works best for that holiday!
DIY wall art project: kids can glue & place buttons inside a simple silhouette shape of larger animal, and sign a gift card with corresponding image (thank you for your silent auction purchase - proceeds to benefit our school)
