Start with a book you don't want any more (or buy it for a few pence in a charity shop). It cannot have more than 100 pages, or the hedgehog will be too 'round'. It makes it easier when it's a paperback.
Start with folding the pages in half. Then fold back the corners, as you can see on the picture.
Continue with all the pages in the book.
Cut off the cover of the book to the shape of the folded pages.
Stick on some eyes and a nose and he's ready! Use a marker for the nose.
You can use this as a letter or postcard holder.
