- If the thread is round instead of flat I simply can't pierce it to lock it.  I just can't do it, not with my eyes and my fingers anyway.

- If the thread is not polyester I can't just burn it to finish a stitch, I have to make tiny little knots with glue etc.  Forget it, I don't always have the required access/room/visibility to fiddle with knots and glue where I'm stitching.  With polyester thread I burn the ends with a lighter, done.

- The needle also has to be as thin as possible, it makes life much easier for the same reasons as the thinner thread.   I bought the whole range of James Jones needles and I use the smallest one 99% of the time.

The trick to piercing round thread is to untwist the bit you want to poke the needle into.

None of the books I've read and almost none of the videos I've seen suggests knots and glue at the end of stitching. But simply a few back stitches, which supposedly is enough for waxed linen thread.

Needles need to be big enough for the thread. And I find bigger ones easier on my fingers. Fortunately I make dog collars...

David,  Bible binding is an interest of mine as well though I've yet to tackle one.  When I do, I plan on sewing the cover.  However many fine bibles are simply skived, folded and glued.  If you are new this might be a good option.  There's a lot to learn.  There's a bible binding book by Diego Caloca Jr.  His book teaches glueing without the stitch as well.

If I were going to sew I'd use .6 ritza25 thread and a 004 harness needle with 3.0 irons, mainly because that's what have. Just make sure the spacing from the edge to the stitch line is appropriate for the size iron.  You could also buy a small awl and spacing wheel and not use an iron.

Sometimes the reason for a longer stitch on lighter and maybe more delicate leathers is you have less chance on pulling your stitches through the leather and you may have many hours already invested in your work.

Hope this helps

It's not just pulling out, but through, connecting the stitching holes.

It probably is to be honest... the problem is we never really how it holds up until a few years later, so I'd rather not have to worry about it.  It's psychological :D

One thing to note is that in the heyday of 18th and 19th century binding, the quires were often stitched to very substantial threads, requiring the "humps" often found on those spines.

I don't know anything about book binding, I make bags.   But when it comes to saddle stitching I found that although it looks like there are a million options, in practical terms there is only one combination that works for me and I use it for everything: 0.6mm Ritza polyester flat thread with the smallest needle I can fit it through.   And it's the only combination that works because of these reasons:

- If the thread is round instead of flat I simply can't pierce it to lock it.  I just can't do it, not with my eyes and my fingers anyway.

- If the thread is not polyester I can't just burn it to finish a stitch, I have to make tiny little knots with glue etc.  Forget it, I don't always have the required access/room/visibility to fiddle with knots and glue where I'm stitching.  With polyester thread I burn the ends with a lighter, done.

- The thread has to be 0.6 because that is the thinnest flat polyester thread I can find.  Anything thicker and I struggle unnecessarily to pass it through the stitching holes, especially when I'm doubling up to finish a stitch or if I have to go back to correct an error.  I will use thicker thread when I start making safety equipment, which is probably never.  Ritza 0.6mm polyester is plenty strong for everything else, I add rivets if it's a high stress area.

- The needle also has to be as thin as possible, it makes life much easier for the same reasons as the thinner thread.   I bought the whole range of James Jones needles and I use the smallest one 99% of the time.

- The spacing of the holes is just an aesthetic decision, when I buy irons I look at their spacing range and I always choose the middle one.  And it's always been fine.  

Totally agree.
