Type of needle for thin pliable leather.

[DG1]

Before getting rid of an old leather couch I salvaged lots of leather from it. Not sure of the weight of the leather but it is reasonably thin and very soft and pliable.

What type of needle is typically used to sew this type of leather? I have both leather needles and regular round point. I know the leather needle should be used for veg tan leather, but what would be better for thinner pliable leather like that used to upholster a couch/chair etc. Is there a disadvantage to using a leather needle that will cut the leather? With the round point it seems like it will pierce and stretch the hole, which will then tend to close up afterwards tightening around the thread (at least that has been my experience hand sewing leather using an awl to make a hole).

Thanks!
