Twin needle help!
Stitches aren't stretchy enough

Hi, I am finally venturing into the world of knit fabrics and bought a twin needle. I just sewed a pair of leggings for my daughter, using said twin needle, and realized the hems and waist really don't have very much stretch. The stitches are definitely going to snap if I stretch them too much. I ended up taking the stitches out and using a zig zag stitch instead, which is so much stretchier. However, I really like the look of the twin needles better. Any idea what I might be doing wrong or how i can get more stretch? my machine is set to a straight stitch with the standard, i guess medium, stitch length. Thanks so much!

Are you using the twin needle just for the topstitching on the waist and at the ankles?

I also have found that a simple zigzag gives more stitch than the usual twin needle approach. You can fake it by using two rows of narrow zigzag with a little space between them.

However, I have learned how to get a stretchier twin needle effect by playing with my machine. The hole in my soleplate is wide enough to permit just the tiniest zigzag with the twin needle, and it is indeed considerably more stretchy than a straight stitch.

Big Cautionary Note Here: I experimented very carefully and slowly on scraps with this one, because you have to feel your way along to see exactly how much play you have to avoid smashing the needles on the edge of the hole in the soleplate.

You can use wooly nylon in the bobbin. You do need to hand wind it, I think.

I think ,your twin needles will be fine for the hems of tops For stretchier things like leggings I use a stretch- stitch of the sewingmachine

I tried wooly nylon in the bobbin to do twin-needle hems on T-shirts. Popped stitches every time I tried on the garment. And the stretch-stitch tended to mangle the thin jersey fabric I was using.

The only thing I've found so far that works reliably is a zig-zag! I'm reading this discussion with interest. I may try to do a narrow zig-zig with the twin needle on my next T-shirt - that idea sounds interesting.

On a waste scrap of fabric, you could try using the twin needle with a triple straight stitch, the one where your fabric goes forwards two or three stitches and then back a stitch, and then forwards again. At least you got some reverse stretch kind of movement in there then. Or you could forget about the twin needle. and just use a single one and sew two rows of a triple stretch stitch or even only one of them. Or the zig zag or even press up and more hand catch stitch from the wrong side in such a way as you see no hem, but doing that while bottom of leggings are more stretched out, so thread would not break later.

The look of the twin needles you like on store bought ones are done with a kind of machine you don't have though, and it has loopers not a bobbin, so you are never going to get the exact same thing with a sewing machine and a twin needle.

My twin needle stitch is not very stretchy at all, if the stitch line really needs stretch, I have to use zigzag.

When I use a twin needle to do hems etc, I always stretch the fabric being stitched.... to the limit, and I us just a straight stitch.
I do not use wooly nylon , on the bottom, as the threads that break are the top ones, unless the bottom tention is too tight. The bottom thread should be "zigzaggy"

I usually play with the stitch length, as different fabrics can work better with different stitch lengths.

I never wind wooly on a bobbin with a hand winder, but I do wind slowly with the machine winder, so that I can control both the stretch and to make sure the thread is evenly spread on the bobbin.
good luck

I have given up twin needle stitching because my bobbin thread will pop when worn-it is just not stretchy enough to accommodate really stretchy material. I have tried stretching my fabric but most of the time it doesn't work; it would mean stretching out my fabric and risking the breakage of my twin needle to get enough stretch in my stitches. I have not tried wooly nylon-trying to wind that stuff on a bobbin sounds like too much trouble. I have been using a very small zigzag which I like. I went to look at my machine because of this discussion. Silly me; it will do about 50 stitches with a double needle-I guess I need to play with my machine more. Mine will do zigzag with a double needle so I might try that to get the double row of stitching. The answer to for me is saving for a coverstitch.

Stretch And Sew! That was the seventies technique for sewing knits to prevent stitch pops.

I guess this was for those who did not have a zig-zag feature on their sewing machines, or if they did, had not figured out that a narrow zig-zag is very, very close to a straight stitch, only with stretch.
