On the first picture at the right I used a splitstich done with hand dyed yellow DMC embroidery floss. The design on the right is made from a blue fruit nett and yellow floss.
On this picture is a variety of stitches. The top one on the left is a coral stitch, next to that an open Cretain stitch. The long one at the right is an interlaced running stitch. The spiral in the middle is a white yarn couched down with a herringbone stitch and the crescent shape is made with French knots.
