Start ut by marking your stitch line on ever piece of leather you will stitch
After it is marked, start your chisel in the exact same spot on each piece. I used to surf in my younger days, I would ''hang ten'
that means i would hang ten toes over the edge of the board.
Hang one, hang the first prong of your chisel over the edge of the leather, If you do this on each piece your chisel prongs will be mathematically lined up
I always stitch right to left. and the first needle threw the hole is the top needle down, then pull the thread to the left, bottom needle up to the right/front of the thread you are pulling out of the way. then top needle down,
Your hole is slotted. top needle down on the rear of the slot. pull to the left. bottom needle up on the front of the slot. DO THIS EVERY time in the same order
If you switch up and top needle down on the FRONT of the slot your stitch line will show it like a neon light
start your stitching going left to righty
top needle down on the left/rear of the slot. bottom needle up on the front/right of slot. REPEAT exactly
