Hello Katuna,
Skizzenbuch is protected to not permit changes to be made, but I did not protect it from being printed. I know most PDF protection can easily be hacked and that is the reason for the copyright. I took Skizzenbuch and had a previous version printed at a print shop on card stock paper and that cost over $200. I since trashed the printed copy because I have made many corrections and additions. I plan on printing it again in a 11 x 17 format on glossy card stock 80 pound paper. I have a leather bound metal post binder (the main reason for the 1.75 inside seam), so the book will be about 2.5 inches thick with the Wallet Folder in the back of the book. The card stock, printing, and the post binder total cost is about $500.
Regards,
Don_
