I also sewed on the button. It was almost too big. It was so wide it barely fit between the foot and the darning plate. And the holes were so wide I had to use the widest stitch.
Here’s a picture of the finished button and button hole.
I made 2 of these at the same time. I thought if one gets dirty, I could bring it in and actually have one.
Also, I had wanted to make these forever. So this is a project I can check off my mental list of things I want to make.
