The orange peel design can be made by doing a serpentine design on either side of the seams down the quilt. You then come back down on the other side in the same serpentine design to complete one row of the petals. There is an exmple with pictures on-thegirlwhoquilts.blogspot.com. She has done one on Cham square under love-u- charm-quilt-and-orange-peel-quilting. Have a look at hers and see if that is what you want to do, if not SITD will be very nice too.
