Keep the wonton wrappers covered before using. If they dry out they will become brittle and break. When folding, eliminate as much air as you can, or it will burst during frying and make a mess. Do not add hot filling to the Potsticker wrapper. The wrapper is so thin it will become soggy quickly. Wrap the Potstickers tightly and add a bit of water to the edges of wrapper to seal them. If the fold is intimidating just wet the edges and fold it over into a triangle to seal.
