Definitely an interesting tutorial, but it only works with a SOFTBOUND notebook. I prefer hardbound to give a bit of support for writing. I made one this summer for a friend.
I only show the finished work, not step-by-step and patterns, but I probably saved my paper plan somewhere.
What I did was make a paper cover to be sure it could be put on and off without a problem. Then I cut the leather pieces and set to work. This is an A5 hardbound notebook, available inexpensively all over the place here in Europe.
If I were doing the project again, I would start lacing at a point where the leather is DOUBLE THICKNESS so I could hide the ends properly.
The design is based on one I found online--probably on the Tandy site, but I can't be sure--but I reworked it to increase the size. Made several photocopies once that was done then my husband wrote the letters on the pattern with a calligraphy pen. His handwriting matched better than any font I had on the computer.
Helps to include the URL to my blog where I posted it.
