Product of the Month: Twin Needle

February 14, 2014


This month's product of the month is the Schmetz Twin Needle. This notion is great for hemming knit garments and gives an elastic but professional finish to your knit edges. The twin needle creates a double row of straight stitching on the right side and a zig zag stitch on the wrong side which is very similar to the cover stitch found on most ready-to-wear knit garments. Twin needles are also great for pin tucks on wovens but that is another post that can be found here. I love the results achieved by the twin needle for hemming knits. I was so over the standard zig zag stitch: it didn't look as neat, professional and it often rippled as I stitched it up. The twin straight stitch adds the finish I love and drastically reduces the rippling. However, I did have a serious issue with tension on my Brother he-120 so I am including all the tips I tried in case you have similar issues.


Let's get started

First my main issue was with my upper thread being too loose and my bobbin being too tight. Even with my tension disc set all the way to 9 (this is where I set it when stitching gathering rows so the bobbin should have been loose as a goose) I was still seeing some upper thread on the wrong side and my zig zag was not taunt. So I tried rethreading just in case it was my error. No change. Then I tried centering my needles instead of just moving them to the slight left of center to clear my foot. I thought if the needle were centered then the zig zag would be pull on both upper threads evenly. No change.


A missed stitch!!


Still wonky

Next, I tried stitching with some light weight paper under my fabric in case it was an issue with the feed dogs. No change. I saw slight improvement when I moved the paper on top of the fabric but not enough.

I then tried using my walking foot and while I saw no change in my tension issue I did see that the tunneling effect was greatly reduced. So the right side appearance was much nicer but the wrong side was not correct and looked "off". Next I tried lengthen in the stitch length. This helped but only slightly but gave a better result on the right side.


Longer stitch length

I decided to take a chance and threaded my bobbin again but this time I did not run it through the guide but I just pulled it up through the needle plate. Since the bobbin tension was too tight I thought this would loosen it up. It worked great and gave me the tension I needed.

This was a very time consuming experiment that involved two machines (the tension issue occurred on two Brother machines) I had to keep tweaking and sewing, tweaking and sewing but finally I was able to create the correct tension and next time it will be so easy to hem my knit garments. Thank goodness spring is coming!

 I have found many posts around the blogosphere that give tips on using the twin needle on knits but only a few were truly helpful. Here are a few of those I found good reads and warmly recommend. Please add you tips in our comment section with how you achieve good results with your twin needle.
