I've used various methods to mark my quilt tops for quilting. I've used Golden Threads paper with the design drawn on it; have also used a product called Quilt on a Roll - not sure if this is the correct title - but it is paper with adhesive strips and the pattern pre-printed. The only drawback to these two methods is the task of picking out all the paper when you are finished!
I just ordered a product made by Bohin called a transfer veil and pen - which looks like it may work nicely for marking a pattern. Hope this helps!
