Letters written out in script

In response to Alum's OP:
Do you have Adope Photoshop or some other picture program?
It should be fairly easy to insert text into a blank canvas in a bold script, and make it however large you wanted it to be for your pattern. Depending on your program, you may even be able to make your text be a hollowed out dotted line such as the greek letter patterns are.
