Depending on dark you material is. I don't have a light box, but a sunny sliding glass door or large window works. You can tape the pattern on the window and then tape your quilt up and trace it onto your quilt. I use a washable marker for quilts. It's a light blue and when you wash your quilt it all comes off. You can also use a very fine pencil lightly and it also comes out. My preference is the marker though, because it doesn't smear and get your hands all dirty as pencil, chalk, etc.
