I used a 2-1 twist of the same colour silk as the foundation whenever I did this before, this time I used a single strand of #1 silver. The metallic thread sits on top of the silk more than the fine twist, which may also be because I stitched the foundation with a single strand of silk instead of two. That was because when I tried it with two strands, it looked heavier than the fore wings.

I am pleased with this; it looks delicate and does not dominate the fore wings. I have twisted a 6-1 pale blue and silver katayori to outline the hind wings, I think this will give a softer edge to the wing. I have also twisted a 6-1 black and silver katayori for the antennae. After twisting, these threads are wound around a glass, dampened, and left to dry naturally before it can be used.
