Love log cabin blocks. Now, for the book's binding that is shot: take it to Office Depot and they will put a spiral binding on it for $3.00 and will also add a clear cover sheet on the outside of the book. I am gradually getting all my soft bound books changed over to spiral bindings.
Turning 20 might be a good beginning block to try also. Good luck in finding the right pattern for you at this time in your recovery.
