I have used the DW fabric that is the same print as what Joanne's carries but I got mine at fabric dot com. I almost never prewash and I have been using mine in an EPP project so have not laundered it yet as it is a looooong way from finished. If you want to add a little something, something extra whims and fancy, fandom in stitches and one other I can't think of right now have some amazing DW paper pieced designs.
