I just posted this on a different thread... no pun intended:
I've watched Armitage youtubes and stitch exactly how he shows but alway get a very pronounced zig zag on the back and a less pronounced almost straight on the front.....and, I'm over it! I guess that' just the way it's going to be. It's neat I can live with it. I used to use a drill press but have switched to chisels to mark the front and an awl to poke through and it looks whole lot neater. I just don' get a real pronounced zig zag on the front.
