I bought a couple of these a few years ago and I liked how well you could see the stitching - I was playing around with thread painting, and you could do tiny, delicate work
But I was nervous about trying to quilt with this type of needle. I had a vintage darning spring attachment which I liked and I had my favorite little $3 hopping foot which I used as much as possible. I wish there was a similar foot that would fit my industrial machine.
Have fun with your spring needle and show us what you do with it.
