Here is a motif I did for my whole cloth wallhanging (seen elsewhere in this blog.) I used 4mm and 7mm silk ribbon for the flowers and 4mm silk ribbon for the leaves - straight stitch for all. The stems are done using Portuguese stem stitch but a regular outline stitch is fine. I used 4 sizes of rose montees to finish. Tip: When doing flowers with straight stitch I always start my stitch at the outside and go in toward the center of the flower. To me, it always seems to make a neater looking flower.
