are you trying to do a new york beauty blocks? if so, do a search for new york beauty tutorials- you should be able to find some good tutorials/videos- here & on u-tube. i've always done them with foundations-not papers (i use lightweight muslin) it does seem as if the paper would make curved piecing a little more difficult since paper doesn't stretch-move as easily...but i'm sure it's (do-able) basically- stitch on the stitching lines- then clip along the curve to within a couple threads of the stitching- then press toward the outside.
