Rubber band binding

The loose pages of this fashion book are held together with just a rubber band. This is kept in position by a notch that has been cut out of the top and bottom of each page. 

 After researching binding techneiques I have decided on this elastic band binding as it is quite uniqu and very easy to do. All you need to do or so I have seen from these images you just need to have an indent on each edge of the pages and then the rubber band wont come off. It would be cool to get some pink rubber bands to tie around the pages.
