Saddle Stitch - How To Change Threads Without Ruining The Stitch Line?

[panchoskywalker]

I'm no expert, I haven't read any book, but this is how I do it.

First when I finish the stitch I don't burn the end, I hide the the thread between leather layers. I work on small things so I just pull the needle between the leather till the other side and sometimes put a tiny amount of loctite just to be sure the thread won't move.

When I do this I don't end both stitch at the same hole to avoid your problem, so the last hole has already 1 thread "layer".

Then I just start from that hole with the new thread.

Again, I am no expert so I'm sorry if this sound stupid.
