I worked on pieces of painted and printed silk with Madeira machine thread. I quite often use machine thread to hand stitch when I want an understated effect and especially when I'm using seeding stitch.
There will need to be decisions about where to go next ... Do I cut the work into even narrower strips and invert some, or hang them in a frame as they are? How to edge the pieces?
I have a very good stitching friend locally who will, no doubt give me her views when I meet up with her on Friday.
When I've decided, I will post the final result.
