On fabrics that are dark enough, I use pounce. On light fabrics, I use a mechanical pencil. When using the pencil's, I find it better to make several 'soft handed' marks, than to try and get it with one pass, as pushing too hard breaks the lead.
Sometimes, I find it necessary to remark the pounce, if it is a long pattern and gets rubbed off while quilting. I hand quilt so have learned to quilt in the areas where my hand will rest first, so as not to rub the marking off as often.
