All samples have been worked on a silk fabric which unfortunately does not photo very well; also I am not sure why some of the photos will and some of them will not enlarge.
The first sample is traditional couching of gold thread, using two threads. The threads in the middle sample have been "plunged " at the ends of each row. The circle is padded with felt, but this does not show up very well, perhaps more layers of felt are needed. The border is split stitch using a silk floss, I found this thread hard to use and the result is a bit of a mess! The sample is 3" X 2"
