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.
