Open a new image, 12 x 12 is fine to start with.
Press D to reset your colours to black and white.
Fill the image with white and then create a new layer.
You should now have 2 layers, the top one empty and the bottom one white.
Make sure your foreground colour is set to black and your background colour a dark grey and select your brush tool and reset it to the default brushes.
Select the Dry Brush Tip Light Flo brush, increase the size of your brush and randomly stamp around the edges of your image, don’t just stamp down once, try clicking a few times to get a more darker stamp impression and play with your brush size too, and of course, please go right ahead and use other brushes if you prefer (rough round bristle is a good one, so are the chalk brushes) and switch between black and your dark grey.
Here is a quick one I did
Once you are happy with your edges, select your smudge tool (press R on your keyboard), change the brush to any of the above brushes, and very slowly smudge the edges, this is very memory intensive so only do a little at a time.
You are going for a smoother look to your images.
You could also try using your blur filter, try Gaussian blur set to around 5, and also try using your motion blur and play around with the angles.
If you have more than one layer for your inked edges, merge them together (no not merge to your white layer)
We are now going to erase parts of your border.
Then using your eraser tool, again changing the brush and size, randomly erase parts of your border.
It’s a good idea to work on a layer mask, that way you can change it if you need to.
Another way to do this would be to create a new layer above the others, then using your brush tool, draw random lines around your border, blur them and add some motion to them, then select the lines and click delete on your border layer.
Once you are happy with your border, you can go to edit-define brush preset and save it as a brush (you might need to down size it), or you could save it as a png (remember to delete your white layer) and then use it as an overlay.
As a brush using a shade darker than the paper
As an overlay in black
Your border will probably look different to mine, and that in my opinion is a great thing.
