Cut out a piece of paper or light card. This is going to be your first page. You don't want the paper to be too heavy. Mine was 28cm long. Cut out 10 lengths in different colours and patterns.
Fold them in half.
Stick them together.
This is my front cover. Cut the same measurements but abit longer. Taking into account that the paper will have made a spine. Fold it roughly around the paper and spine.
Before glueing together add a ribbon to the sides. And then put all the paper inside, glue and press down. Leave to dry.
Enjoy your new journal.
