The red thread defines the 8 mm spacing for the SSH.
Unfortunately it was impossible to see the every 3rd thread for the SSH, especially with the blending in place. So I added guide lines for the angle and I'm using the ruler to measure 2.5 mm for the SSH. I only need to do SSH for the lighter red.
I have the SSH done on the left side, and most of it on the right side. I can either do the blisters flowers next or continue on the obi around the waist.
