It took me a while to decipher the instruction from Barbara Walkers’ A Treasury of Knitting Patterns the BTT Back Twist Two stitch. I was making the Twist Zigzag (Chapter: Twist Stitches, p. 119) swatch for the Walker Treasure Project and wanted to follow the directions as closely as possible so I could faithfully reproduce the swatch.
I did some web searches and could not find any helpful information for this stitch exactly the way Mrs. Walker has instructed and after some trial and error I believe I figured it out.
Here is my interpretation of the twist stitch. I wish the pictures were a little better, I will update this page if I can get better results with my camera.
