@desiree Looks to me like (doing same thing to all the bustle pieces, like an assembly line) 1. put a narrow hem on the bottom of the half circle. 2. stitch that dart shut up top of the half-circle. 3. Fold the half circle into a quarter circle so that the two dots touch each other. 4. Turn the bottom edge of the quarter circle upwards like a hem. 5. Open out and pin two together, then sew the long curving edge of the bustle piece. 6. Gather and stitch into place on the bodice. Good luck!
