Always test new marking pencil on fabric scraps to make sure they are removable. Are you hand quilting or machine quilting? If machine quilting, you may want to look for some Golden Thread quilting paper or rip away preprinted designs. Some people take squares of tissue paper and pencil the design on the top square. You then stitch through the top paper with your machine needle without thread down through the stack. You then have a stack of duplicate patterns with a punched needle design you can follow. You pin the tissue to your block and stitch through the paper and pull it off when you're done.
You can also FMQ (free motion quilt) a design that follows the piecing pattern. SITD(stitch in the ditch) along the piecing lines is also an option.
