My wife mentioned that she didn’t have a nice notebook for meetings at her new job. So I grabbed a spiral bound notebook and cut this in some plywood I had around and glued some heavy weight scrapbook paper to give the design a background and a little extra strength. Next time I’ll have to see if I can find some thinner plywood. It was 2.8mm and with a front and back cover made from it I was just at the limits of the spiral functioning.
Very nicely done!
