Alright, well, as you may have noticed, this tutorial is pretty much a walk through of the tools and techniques I use when making something like this....
Step 10: Stars and stuff
Add any other bits and pieces you want, I added some stars, and to do that, take a look at the picture below, set something similar up to it and then position it in the bottom left corner and drag stars to the tips of the lines.
In this last image you can see that I rotated the stars so that they fit the curve. My own preference, you don't have to do that if yu don't want to.
