I stitched another circle design from my circle design sketchbook. The thread is Perle Cotton in sizes 5 and 8. That is my favorite thread. It is easy to use, comes in a number of thicknesses and lots of colors. The stitches are Chain stitch, Back stitch, Straight stitch, and some straight stitch couched because it was too long a stitch not to tack it in place.
I keep being challenged to decide what to use where color and stitch wise but have found that the designs have turned out just fine.
