I’ve made 1:6, 1:3 and 1:1 books, both readable books and “dummy” books [to fill the shelves], mostly by studying the construction of my own books and working outwards and backwards to create my own from scratch. For an impatient person with no training in booksmithery, I’ve done pretty well.
I should now graduate to leather-bound books, with endpapers and spine ridges and all! I should also take pictures of my readable 1:6 and 1:3 books. Heck, I should even start making 1:1 books, especially since I go through them so quickly.
