Dip your finger into the bowl of water and draw a circle around the exterior of the wrapper. Lay the wrapper on your left hand. Add about 1 1/2 to 2 tablespoons of filling in the center. Starting from the right side, start sealing the wrapper together, until you reach the center of the dumpling filling. Then, use your left index finger to push the unsealed part of the wrapper towards the center. Seal the dumpling. Refer to the photos or this video
for visuals on how to fold the dumplings. Place the sealed dumpling on the baking sheet and cover with a cloth. Repeat this dumpling making process until you have used all the dumpling filling.
