Depending on how detailed the design is and how you are planning to hoop it, or not.... You can use white contact paper cut out shapes stuck onto the quilt temprorarily and move them along as you go. That way there are no marks at all. Like a mellon shaped chain, for example. There is the tear away iron on paper you can quilt over and tear off too.
Check in the quilting notions section of say nancy's notions, on line. There really is tons of options.
