Book number 33, circular book

Current bid for this book stands at £15

After a flurry of making books over the last week or so I had an idea to do something slightly different and here it is - a circular book. A group of pages folded together is called a signature, and several signatures sewn together create a book. This time I had lots of signatures and no covers, so I kept sewing them together and joined them to create a circular book.
The book measures 5.5cm high and is 13cm in diameter. There are 384 pages.
