Yes indeedy! What you are doing is trapunto. Sharon Schamber has a you tube video I believe in doing this? I like to use water soluble thread since it washes when the quilt is done but matching your thread to the background works too. I lay my batt behind what I want trapuntoed, stitch all around the outline, flip the top over and carefully trim away the excess batt. I then sandwich my quilt as usual and then stitch around the outline again to quilt the quilt.
