Here is just one suggestion for you.
There is a product called Quilter's Preview Paper made by Quilter's Touch @
http://www.quilterstouch.com/previewpaper
It isn't really a paper as much as a roll of thicker plastic with black borders at top and bottom. The idea is to put this on top of your quilt and use a felt tip pen to draw your quilting design. The black borders are to prevent you from drawing on your quilt. You can easily wipe off the pen drawing and start again. This way you can play around with what you think you like best on your quilt. Once you try it you'll love it.
