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 morning I descided it was time to change my windowsill. I always get a lot of compliments from strangers. "They always like the things I do with my window". not sure if I will leave it like this till easter.
