Fabric 'n fibre postcards: Day 39

Because my brain is still in meltdown after seeing those 100 artworks at Gallery 159 yesterday,today's message is brief:

Bobbin thread:
I use a cone of clear 100% Nylon or "Wonder Invisible thread" made by YLI Corp. in my bobbin.
As I stitch on the design side before sandwiching my card layers,the bobbin thread doesn't show through.
I also have (Janone) bobbinfil in white and black,but find the clear to my preference.
And when I satin stitch the edges,no contrary colours appear.
