Gorgeous, gorgeous!!! I can't give any advice on how I would do it, because I think I would be in the same situation. I do have a site bookmarked that sells quilting stencils and maybe by looking at these something would just pop out and say ME ME!!!! I know I sit and look at all my quilt quilting books and then I still wonder in a daze.

Good Luck!!
