I have created a Roland Laptop Cover Tutorial for you which is a step-by-step guide on creating a graphic that could be used for a laptop cover.
The tutorial takes you through starting with a sketch/idea and finishes with applying the final piece.
A VersaUV LEC-330 was used for the example although the principles could be transferred to other machines.
Once you have clicked on the link you can opt to go full screen should you wish, and simply use the arrow keys on your keyboard or click on the ones on screen to navigate your way through the tutorial.
There is a little house that will pop up on screen if you hover over which will take you to the home screen of the tutorial, and also zoom keys if you would like to see any bits close up!
I hope you find it useful, and should you create any of your own be great to see them!

Will post a pic when done
