My hubby bought me Keith Smith’s Non-adhesive Bindings Volume 3 last year for our anniversary and I finally got around to learning the caterpillar stitch. (which was the whole reason I wanted the book in the first place.) I took some time today while waiting on things to dry on the commissioned book that I’m working on to figure it out. It took me several tries to get the start of it but once I figured it out, it was fairly easy.
Here is a pic of the sample card that I made.
