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!
Card making: This I LOVE U card would be great for Valentine& Day or just to tell someone you care. Print the template and cut the solid lines with a sharp knife. Don& cut the dotted lines. Those are there to show you where to fold.
