I don't have a machine, so all of my sewing is by hand with a sewing awl from Tandy (the kind with the thread on a small roller) I use a waxed linen thread.

I have used a 4 prong punch a couple of times, but I don't like it much. Mostly I use a rotary prong round punch. I scribe a line a given distance from the edge of the leather and then place the punched holes centered on this. For spacing, I punch the first hole, then lightly position the punch next to this and make a light impression. Then I punch the next hole at the edge of the light impression. Continue light impression and holes to the end of the stiched line. With a little practice, it goes well. I use the same system for lacing. I generally use the 3/32 inch wide lacing.

Thanks to all for your comments. I've learned some new things to try.
