The buttonhole stitch (or blanket stitch) is a stitch that I never really use. I always see cute flowers stitched using the buttonhole so I decided to try it out.
I traced flowers from this free pattern with water soluble ink.
I found the pattern on the French Knots free vintage patterns blog (which you should definitely check out - there are tons of embroidery patterns!)
After I was done stitching I dunked it in water to remove the blue tracing lines.
Yellow french knots for the centers of the flowers. All stitched with 3 strands of DMC floss.
