If you want to fade the edges of a layer in Photoshop, there are a few things you can do. You can use the following steps to fade the edges of a layer:

  1. Choose Layer > Flatten. This will flatten the layer and make it easier to work with.
  2. Choose Filter > Blur > Gaussian Blur. This will blur the layer and make it more realistic looking.
  3. Choose Filter > Noise > Lowpass Filter > Noise Floor (if you want to add some noise to the layer). This will add some noise to the layer and make it more realistic looking.
