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!
Maybe next year's Mother's Day? Flower Pot Card - Idea: Cut out the card from cardstock as it is, and fill in the flowers appropriately and artistically with quilled shapes. Fold it and add your message inside!
