Japanese book binding
This is a very simple and beautiful style of binding a book. i have done a soft back version, but it can be done using card to thinker the cover.
all of the stock is the same size, i have used a different colour stock for the cover the define it.
You then use one of the pages to create a template by folding it 3 times horizontally and leaving two folds between each hole. using a pin i pierced though a hole.
i then used cotton thread to sew the pages together.
