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!
This hatching spring chicks craft is just the cutest and is so fun to make! You'll just need a few craft supplies, and the post even includes a free egg template to make creating this project even easier.
