Then, access the Effects panel.

Step 2: Add the Textures filter

Click Add Filter and choose Textures from the list.

Step 3: Add the Analog Grunge border

Using the Category dropdown, choose the Analog Grunge option from the list. (This category name will be whatever you named your category when you imported the files using the Manage Extras window.)

Then, use the Texture dropdown to select the border you want to apply.

Step 4: Adjust the texture settings

You can also use the Transform settings at the bottom of this filter to further adjust the positioning of the border over your image.
