The third uses ribbons and threads trapped between 2 layers of soluble fabric.This was oversewn by overlapping horizontal rows of whipped zigzag, vertical 3-step whipped zigzag rows and then a top layer of normal tension straight stitch with gold in the top.
The second uses a very open grid of straight stitch oversewn with areas of zigzag in white and trailing linking threads.
I have continued making these to represent my drawings. In the first I have made 2 samples to represent a glacier. the smaller sample uses metallic thread in the top, blue thread in the bobbin and a normal tension straight stitch grid. In the larger sample I have changed the top thread to white and tried to create depth and texture with very dense stitching.
