Joann Fabrics has a great assortment of different Star Wars fabrics!  When I wanted Star Wars fabric for a project last fall, I could not find anything - ended up have to use an odd twin bed sheet - so I was happy to be able to stock up now.  
I'm not much for sewing, but I did take a few hours to make my boys PJ pants with one of the fabrics. 
 
This is a very easy project - I have a Singer Stylist portable sewing machine.  I used Simplicity "Learn to Sew" pattern 2290.  You get patterns for child and adult pants in the package. The instructions were easy-to-follow.  I needed to add a fair bit of length for my tall, skinny kids, and the instructions covered that.  Be sure to wash, dry and iron your fabric before you start.
