yes, I just dont have it in my old machine..

Ok

O.K. So
I think I realized my mistake in the finish.
And I also changed the seam most similar to a triangular zigzag. Intentionally in a white thread that will stand out
Hope this is true
Better with this zigzag?

Hello. I have not tried this seam, it may work well. We use a triple zigzag, which is found on the overwhelming majority of sewing machines. I have circled it with a green line on the diagram.

I know but dont have it in my machine
any wey I fix the keyhole.
I will have to buy a new machine

You can try 2.

Here is No. 2
I had to reduce the width of the seam to 1.5. Not to be too wide.
Maybe a few millimeters more
What do you think ?

I like it, it is good enough.

o.k so
This is my last one I love it !!

Now I have a question
If I do not want to make a collar and not a scoop
But a small scoop and a keyhole.

I have not seen this option. Did I miss it? Or it's not really demonstrated.
If it is not demonstrated can you please explain?

The principle of processing is the same as for the drop, only we turn the seam on the wrong side.

So the seam become on the top line? did I got it?

and Without rubber

o.k. Idone it.
thank you

us it the same with no sleaves?

Yes, it fits for sleaves too.
