Neat! I had never heard of that before.
I'm a Hollander, so dunes are more the tall peaks I grew up around. But deep down I'm a mountain boy at heart.
I'd had the idea of sewing this on the side of a cap, as a bit of an homage to Gebirgsjagers. But it's a little too big for that. May try to do another one about 2/3 or 1/2 size.
I've been having a blast with embroidery, and to a large degree it's just about trying what's possible, striving to learn more, push the envelope, etc. This was one idea, and beyond anything, I just wanted to see if I could do it.
