I made an Indian cross stitch cowl for my mom. It is super soft and perfect for around the face. My only issue with it was when I was winding the yarn the yarn was all tangled and instead of winding into a nice ball like the first one it has ended up a big pile of mess!
I used these to knit two at a time toe up socks. The cable was nice and flexible and the area where the needle and the cable meet is really smooth. The cubical shape is great. I find that the cubes are easier to hold and pick up stitches. I liked it so much that I went and bought more! I will say in terms of price these needles are a great value.
