Your flatlocking is gorgeous and I am absolutely smitten with the yellow and gray fabric that you used. Your scarf is beautiful! Very well done!
I'm so happy I got that flatlock stitch down.
I wish I could do the 2-thread detail, but since I can't I finished with a 3-thread narrow seam.
I love the fabric too, but it's wool, so a little thick. I want to try another one with a lighter fabric.
