I just made the holes in the one piece with a stitching fork and poked them through with an awl then hand stitched them. It looks a bit neater in the photo than it does in real life
I made a few mistakes on this project but learned loads too, like I really need to get some flat nose pliers to pull the needle through rather than use my hands. My poor fingers were shredded by the time I’d finished.
Here’s a couple of things I made out of scraps while waiting for new leather to arrive. The pin cushion is stuffed with a couple of discs cut out from a foam kneeling pad.
