Step 1 - went out and bought a copy of Digital Photo Magazine with a DVD of PSE Tutorials (actually, it was the 40 border templates that caught my eye)
Step 2 - had a play with some of the tutorials on the free DVD following the instructions in the magazine.
Had great fun - not sure I totally understand why/how it worked, but as long as I can achieve the effects I guess that's the important part.
Here's a couple of piccies of my results :)
