I will tell you how to finish the thread after the machine works.

The method to thread a needle is to thread the end of needle to make the tip of needle penetrates the thread two or three times.

When you pull the end of thread, it will bring the needle. Then it is completed.

There are many ways to finish the thread.

I will show a few cases for this time.

Shall we find out one by one?

1. Double finish by connecting the last stitch

You may need to connect the end with the stitch you started after finishing the machine like the photo. In this case, penetrate the last stitch to the start stitch to complete.

You can make a strong stitch by doing double stitching in one place. You can just stitch for the first time and make one more stitch. Then make a knot with cross by using the thread that wasn’t threaded among the two threads.

And add wood glue on the awl

Apply it to the end of the thread.

Now pull the two threads out front and back.

As the thread is pulled, the wood glue is permeated in the thread knot. Then, attach two threads and the leather firmly after drying.

Cut the remaining thread and burn the tip of it with a lighter so that the thread is not unwound.

For reference, component of thread is polyester. So when the fire is applied, the end will be rolled in.

An image of mothers used a lighter for the unwound thread came to me.

Same for the front part. Cut the remaining thread and burn it with a lighter.

Don’t leave the end of burned thread. If you pull it in between the needles holes, the end of the thread will not be seen, and the chance of loosening the thread will be low.

The process of using wood glue for double stitching may be a little annoying. But it is a firm way to finish the thread, so you’d better to use this method when necessary.

2. Double finish of the start stitching

You can use double stitches for the start stitching like the last one.

Since the stitches in start and end part of pocket are likely to be cut due to the frequent use for putting things in and out, you’d better to wind the thread at least two times in place.

Of course, it is possible to stitch two or three times continuously in the same position with the machine. But, the thread may be cut while a sharp needle is continuously inserted into the same hole. And the outcomes are not as satisfied as hand processing. If you make a double stitching with a hand, you can make more even and pretty knot without overlapping each other.

The difference between the products of luxury Goods Company and general products can be seen with this small stitching process. So even if we use the machine, we usually finish this part with a hand as possible.

If you make double stitch in front of the last stitches, it will be more strong finish. The part that receives more force like the patch part that connects the strap can be finished with double stitches like this.

Strap patch part of H Company. You can see that the part that receives the force has finished with d

This time, I will put the thread out to the invisible side, and cut and burn it with lighter.

This time, I didn’t use the wood glue.

3. Finish after pulling the thread back and bonding

If you pull the lower thread like the photo, the upper thread will come out together.

You can pull both threads on the back tightly and finish them when you bond the folding later, not finishing right now.

This method is mainly used when there is not much force applied.

It is the weakest finish in the actual finishing, but this method is used a lot because it looked like a single stitch as well as its simplicity.

4. Finish by making a knot after pulling two threads on the back

If you are worried that thread will be unwound for the method 3, you can make a knot.

You can arrange this knot by applying bond like you do bonding.

But when you make a knot, there is a risk that the stitch will be stuck on the knot when sewing the machine later.

Another thing to be careful about is that the knot of thread should be done like the photo because it is stronger.

If you cross the thread like this, it is likely to be unwound.

This seems to be knotted, but it can be untied easily for the polyester thread.

If you tie like the photo, you can check that it is easily unwound when you take the stitches out several times with awl.

If you need to make a knot with cross like above due to the short thread, it is recommended to use wood glue.

Teacher Mao was very cautious about just tying with cross.

It means that even if you don’t make sure of this minor finish, it will ruin the entire bag even if it is well-made bag.

Should not our lives be the same?

It’s small and simple, but it should be done right and it makes the entire things right.

I’m now over 40 years old, but I’m still learning about the life while doing leather craft.
