In my cover stitch class, I often hear women say they have owned a machine for years, but it hasn't been out of the box! Are we intimidated by this funny looking machine? Often, we don't get lessons on the machine when we buy it. Or we get a quick lesson on how to thread it and make it go, but not how to really do anything. Does that sound familiar?
One of the most frustrating things is to finish a hem, then pull what looks like a loose thread, and then disaster happens. If the final stitches in the row are not dealt with, the whole hem will unravel (oooh... yes, it will!) Then you and that machine will lock horns!
Some machine manuals suggest for you to always overstitch the stitches. What's overstitching? That's when you stitch one side seam on a T-shirt, for example, then cover stitch the bottom hem, and then serge the other side seam after. This overstitches the ends of the cover stitch, catching the thread ends in the serged seam. It is easy to do, and can be ok for some things but to me, it is not very professional looking. It is much better to do a hem in the round.Sew the side seams first, then do the hem. Makes sense, right?
However, cover stitch hem in the round means you must lock the stitches. I use the following technique to lock the stitches every time I come to the end of the row I am stitching, whether in the round or flat. Here's how:
When you stitch to the end of the fabric, stop stitching and raise the needles to the highest position.
Next, raise the presser foot lifter. This will dis-engage the tension discs and allow the threads to be pulled easily. Hopefully you can see below that the foot is lifted!
Now insert some kind of small, thin tool, such as a bamboo stick, a thin awl or the small Allen screwdriver that is packaged with some machines, and use it to go under the foot. Whatever you use, has to be thin enough to fit between the foot and the fabric.
Pull the threads forward until you can see that there are two threads wrapped over the Allen key. Those are your needle threads.
When you have pulled the threads out a few inches, cut them, so there are now 4 thread tails.
Pull the fabric toward the back of the machine. The bottom thread is still attached but the top threads will automatically pulled to the back side of the work.
Cut the bottom thread. The stitching is now locked and the machine threads are in position for you to start again.
Whether you sew a straight run of stitching, such as shown here on the straps, or stitch in the round on a hem, you should lock the stitches exactly the same way.
A cover stitch machine can do these wonderful, professional looking hems - try this locking technique in your next project so you won't lock horns with your cover stitch!
