The twin needles create 2 parallel lines of topstitching and a zigzag stitch on the underside. The zigzag stitch helps maintain the stretchability in a knit hem. All the examples of twin needle stitching I could find showed a zigzag underside stitch where 2 different threads were visible. If your stitching looks like the above picture, you shouldn't need to adjust the tension.

If you notice sporadic bubbling in your topstitching, it probably isn't a tension problem (that would give you consistent bubbling). If you look at the zigzag underside of the fabric, you should see that your stitching is way past the raw edge of the hem in the areas of the bubbling. You just want the top row of stitches to catch as close as possible to the raw edge without going past it.

    Thanks so much — I’ve used the twin needle before and had good results, but your pictures and tips about the zigzag setting gave me some new information that I’ll look forward to using!

    I also use this technique when I attach the bias binding on necklines on childrens’ clothing, folding the bias towards the front and top stitching into place. Varying the colors of cotton make this particularly attractive. The stretch is great here.

    Thanks! I’ve been wanting to give this a try, this tutorial has answered some of the questions which kept me from giving it a go. Hope you’ll do a follow-up on this, I’d love to find out how to make a corner for example!

    Thanks so much for a clear & concise tute. I purchased twin needles in a couple of widths and sizes but haven’t had the courage to try them out yet. Now I have the confidence I need to open up a whole new world!
