Turn one apple into a swan by slicing it in half first. Now, cut down toward the core until you hit the butter knives. Then, turn the blade and cut out a chunk. Do the same on the other side to create smaller slices. Then, spread them out carefully to look like a wing. Repeat the same on the other side. Carve a small groove in the body and shape the other half into a head before pressing in two seeds for the eyes. Then, place the head on top of the body, giving you a swan made from an apple.
