Here is my latest creation:

The book is made up of 6 signatures of rough hand-torn sketching paper, 72 pages altogether. It is held closed with an elastic band.

Inside there is room for a pen and a loop of elastic to hold it in place.

The boards are covered with red library buckram and lizard-skin patterned book paper and it is sewn together with waxed red sewing thread, using Coptic stitch (also known as chain stitch).

I'm thinking about adding pockets inside the covers, to hold stuff like postcards, stamps and boarding passes.
